GeoStudio 2012 is now shipping

March 6, 2012
We are pleased to announce the immediate availability of GeoStudio 2012.
Using GeoStudio 2012 will enhance your workflow and productivity, as well as broaden the types of engineering problems you can analyze. Together with GeoStudio 2012 and in response to many customer requests, we are also pleased to announce a new Annual Maintenance program. Purchasing Annual Maintenance will provide you with a year of software updates, technical support, and other benefits, including any major version upgrades.
GeoStudio 2012 incorporates enhancements to each product in the GeoStudio suite, including:

Improved Solvers

Each Solver has been directly integrated into GeoStudio via a new Solver Manager window.
This lets you monitor the progress of the Solvers without leaving the GeoStudio environment.
Each analysis is verified automatically before solving, and any errors are reported immediately. While solving, you can see the solution status of each analysis, check the analyses that you wish to solve, and stop the Solver. Errors encountered by the Solver are reported in the window.
Solver speed has been improved for all products, particularly when you solve multiple analyses simultaneously. The SLOPE/W Solver has been totally revamped to taking advantage of modern multi-core processors. This results in significant speed increases, particularly for probabilistic and Newmark analyses.

Improved Convergence

The finite element convergence schemes have been improved, allowing for faster solve times and more reliable convergence that is easier to understand. Improved under-relaxation schemes allow you to obtain solutions for highly non-linear problems. The review boundary process has also been improved, frequently reducing the number of review loops required.
You can monitor the convergence history directly in Results view after each time step has completed by plotting the number of unconverged nodes for each iteration or time step.

Improved Modeling Environment

New docking windows in GeoStudio 2012 allow you to view information in multiple views so you can quickly access the data you need. You can customize the display of docking windows to suit your particular needs. A new status bar provides both view information and quick access to commands such as zooming, and a progress bar during lengthy operations such as solving.
Watch a movie showing the new docking window support in GeoStudio:
Introduction to Docked Windows (3:35)

Docking windows include an Analysis Explorer, Solve Manager, Result Times, Slip Surfaces, and Sensitivity Runs.
  • The Analysis Explorer displays a tree view of the analyses in the project, allowing you to quickly change the analysis you are viewing.
  • The Solve Manager allows you to solve one or more analyses and watch their progress even while continuing to work on another analysis.
  • The Result Times window displays a list of time steps that have computed results. When you select a time step, all currently displayed views and dialog boxes show the results computed for the selected time.
  • The Slip Surfaces window displays a list of SLOPE/W computed trial slip surfaces. When you select a slip surface, the Results view will show the complete slip surface results. If detailed results are unavailable, GeoStudio will compute them on-demand, allowing you to view detailed forces or graphs on any particular slip surface without having to designate it as a "critical" slip surface.
  • The Sensitivity Runs window displays a list of runs performed for a sensitivity analysis. Each sensitivity run is now a complete slope stability analysis, allowing you to view all computed slip surface results for each individual run.

Improved Viewing of Results

Results are now automatically displayed when you start solving a GeoStudio problem. Graphing results over time can be done as soon as each time step is computed, without waiting for the Solver to finish. These graphs can also now be generated as much as 20 times faster than in previous versions, and additional SLOPE/W graphs have been added. SLOPE/W results can now include computed finite element data. For example, you can show the critical slip surface on top of pore-water pressure contours, stress contours, or the liquefaction zone. You can also show color gradients when plotting factor of safety contours over the grid of slip surface centers.

Improved Probabilistic and Sensitivity Analyses

SLOPE/W Probabilistic analyses can now be done on every trial slip surface, resulting in an improved understanding of the overall risk of failure. Likewise, each sensitivity run can be analyzed in detail, allowing you to view all slip surface information for all sensitivity runs. Both probabilistic and sensitivity parameters are applied separately for each analysis, allowing you to set up multiple scenarios within the same project. You can apply probability or sensitivity to any pore-water pressure option, not only piezometric lines.

Improved Licensing and Delivery

GeoStudio 2012 is now being delivered to you completely electronically, without any physical packaging. This eliminates your shipping costs, speeds up and simplifies the purchasing process, and is more eco-friendly! All GeoStudio resources, including engineering books, are digitized and available online. Full-color printed books can be ordered separately as required. Stand-alone licenses no longer require a hardware dongle attached to your computer; you simply activate your computer to use your GeoStudio license. To use your GeoStudio license on a different computer, you can either use Remote Desktop or transfer your activation to that computer.

Floating licenses are now controlled using a new license server with a web-based monitoring interface. The new license server can be "re-hosted" onto new server hardware using an included activation utility.

Automate GeoStudio with GeoCmd

GeoCmd is a new command-line utility that makes it more convenient to work with large numbers of data files. You can automate GeoStudio to solve, upgrade, or generate reports for many project files sequentially.

Save Files in GeoStudio 2012 or 2007 Format

Files created in GeoStudio 2012 can be saved as GeoStudio 2007 files, allowing you to continue working with other members of your team who have not yet upgraded.

Additional Enhancements

Many other improvements have been made in GeoStudio 2012, including:

  • SLOPE/W results are now stored in standard CSV files, making it easier to import results into a spreadsheet for further analysis.
  • SLOPE/W analyses now focus on a single method, making it easier to navigate results. The GLE method is now directly incorporated into the Spencer and Morgenstern-Price methods, allowing you to display factor of safety verses lambda plots for these methods to understand convergence.
  • SLOPE/W Reinforcement properties have been changed to match industry-standard nomenclature.
  • SLOPE/W now contains a "High Strength" material model, making it easier to model impenetrable structures such as concrete retaining walls.
  • You can now specify the SLOPE/W residual water content directly; previously, it was assumed to be 10%.
  • Meshing improvements result in better element shapes, especially in complex regions.
  • GeoStudio takes less time to start; several key commands and dialog boxes also have speed improvements.
  • GeoStudio Add-Ins now support Microsoft .NET 4.0 and Visual Studio 2010.
  • Sketch lines can now be shown in color.
  • Sketch axis label coordinates are now shown as actual values, not with "x 1000" labels.

Bug Fixes

Many bug fixes have been made throughout all products to improve performance and stability.

What’s New in GeoStudio 2007

GeoStudio 2007 is an integrated tool for running GEO-SLOPE's leading suite of geotechnical modeling software products: SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W, CTRAN/W, AIR/W and VADOSE/W. It will run on Microsoft Windows 2000, XP, or Vista.
This document describes the significant benefits of the GeoStudio environment, as well as the engineering enhancements made to each product since the 2004 (version 6) release. The new features are based on extensive feedback from our software users. We are also introducing AIR/W as a new product in the GeoStudio suite. We hope that using GeoStudio 2007 will increase the types of problems you can analyze and make it easier to model geotechnical problems on a routine basis.
 

◎Enhancements to all GeoStudio 2007 Products

Product Integration: Multiple Analyses
Multiple analyses of similar or different types can be done in a single project file. Different solutions can be compared in the same file.
Staged Analyses
Staged analyses can be done for construction sequencing with moving boundary conditions.
New Meshing
Take control of your mesh with new meshing patterns, such as unstructured quadrilateral patterns, with flexible fine-tuning options. Interface elements can be added on lines to model soil-structure interactions, liners and geo-fabrics, cutoff walls and wick drains.
Reporting
Generate a report for any analysis, summarizing all input data including geometry, material properties, functions, etc. The SLOPE/W report includes a summary of all results for the critical slip surfaces. With the click of a button, bring your input and results summary directly into a formatted Word or HTML document. Edit and add screen captured images to further enhance your report or presentation.
All New Graphing and Contouring
Graphing has been re-designed with saved graphs, cut lines, and multiple series plots. Define a results graph on a geometry object (line, point, or region) or on any arbitrary line or plane cutting through your geometry. Superimpose multiple graphs to compare data. Create many different Contour views and save them by name.
You can make a contour plot in DEFINE to show your exact initial conditions that will be applied in the model. This is useful if you have various sources for initial conditions, such as previously solved data combined with new soil "activation" values. New Add-In Functionality
Write your own functional relationship or constitutive model. Your Add-In-written in Visual Basic or any other .NET language-can now use custom data parameters to read data from memory or write data to the solver's results file for later contouring or graphing. A Software Developer Kit (SDK) can be downloaded from the website to learn all about Add-Ins and to get started writing your own. New Searchable Examples
Many new examples have been created for each product. Each example now comes with a detailed discussion on how to use and apply the relevant GeoStudio features and how to interpret the results. The examples can be searched by keyword from the start page of GeoStudio or on the geo-slope.com web site. Windows Explorer Thumbnail View
GeoStudio now supports the Explorer thumbnail view, displaying an image of the last saved view of your model.
Network Licensing Improvements
Licensing is more fault-tolerant on a wide area network. A network license server can now be unavailable for a short time while GeoStudio has a license checked out without immediately forcing GeoStudio to shut down. When a network license cannot be checked out, a list of users currently using the license is displayed.
Network license borrowing is now available by request.
New Geometry Based Modeling
Define your boundary conditions and material properties on your region geometry, rather than on the finite element mesh. This allows you to freely change your model without worrying about losing your existing model definition. For example, if you increase the height of a soil layer, your boundary conditions are moved along with the soil, and a new finite element mesh is automatically generated.
Material Models
New material models are available in all products. User Add-In constitutive models are now available in SIGMA/W. Material models and boundary conditions are tied to the geometry, not the mesh. Updated Sketch Text
Sketch Text can now be linked to any or all analyses in the project file. Dynamic Sketch Text can be tied to all solver results data.
Animation in CONTOUR
Make a movie of your analysis to visually communicate how your results change over time. Include dynamic sketch text in the movie that is updated at every frame.
Improved Function Definitions
Function definitions have been vastly improved, including graphing multiple functions on one plot. Define a Spatial Function that varies with the x and y coordinates. Spatial Functions can be used to vary strength properties in SLOPE/W, or for any initial condition parameter in the finite element models. You can now define custom Add-In functions in all products. Write your own material property or boundary condition functions using internal solver data or data from outside GeoStudio. Link your function live with Excel or any other .NET program.
Region Face Boundary Conditions
Apply a boundary function to a region face, so that the volume of the element is used to apply a mass load to the model. You can model source or sink values that are tied to element volume, not just edge length.
 

◎SLOPE/W 2007 Additional Enhancements

Spatial Functions
Unit weight, C, Phi and pore-water pressure can vary as a function of the x or y coordinate using a Spatial Function in a modified Mohr-Coloumb Spatial Model.
Automatic Water Force and Pressure
You no longer need a no-strength water region. SLOPE/W will compute the pore-water pressure on the ground surface and generate the correct water weight load. Visual feedback shows you exactly what the solver is applying in the model. You can override or modify the water weight with a surcharge load. Improved Data Entry
Entering material properties and other data is now faster and less error-prone. Changes made in dialog boxes are now accepted as soon as you enter them. There is no longer a need to click a “Copy” button.
Rapid Drawdown
A total stress staged rapid drawdown procedure has been added. Simply specify the total stress strength parameters and the amount of the drawdown.
Strength Due to Suction
You can specify a maximum suction value above a water table, and the shear strength arising from the suction can now be related more realistically to a Volumetric Water Content function.
Transient Stability
Linking SLOPE/W to a transient SEEP/W or SIGMA/W model allows solving for factor of safety versus time.
Multiple Analyses
You can do many analyses within one project and save all the analyses in one data file, making it easier to keep track of your different scenarios. For example, you can evaluate several reinforcement designs to see how each alternative affects overall stability. Using multiple analyses also improves the ability of SLOPE/W to integrate with other products.
Collapse Surface
A collapse surface can now be defined for loose soils together with steady-state strengths. This information is very useful for flagging zones of potential liquefaction and zones with a sudden loss in shear strength.
Improved Graphing
When creating graphs of your results, you can now decide which variables to show on the same graph. For example, you can plot both total and effective normal stresses along the slip surface. You can create many graphs and save them with the data file. This allows you to instantly retrieve the graphs the next time you open your file.
 

◎SEEP/W 2007 Additional Enhancements

New AIR/W Option
AIR/W can be used inside SEEP/W to account for (ua-uw) matric pressures. Model tunneling under air pressure, soil vapor extraction, and convective air flow in coarse materials by linking with TEMP/W for density effects.
Material Models
New material models such as 'fully saturated/unsaturated' and 'saturated only' have been added. There are also new interface models for liners, barriers and cutoffs. You can now easily add wick drains to your model.
Add-In Functions and Boundary Conditions
Define your own custom Add-In functions that can be applied to boundary conditions or materials. This feature will allow you to include hysteresis in your analysis, for example.
Multiple Analyses in a single file
Multiple analyses in a single file means you can have steady state and transient analyses in the same file. Change the mesh and re-solve the entire project in one step. Link analyses together to account for construction of tailings dams where soil is added and boundary conditions move with time.
Other Changes
  • Boundary conditions are preserved if you change the mesh.
  • New time stepping setup and results saving scheme.
  • New built-in sample soil property functions.
  • New options for Van Genuchten functions.
 

◎SIGMA/W 2007 Additional Enhancements

User Add-In Constitutive Models
Define custom Add-In constitutive models in SIGMA/W. Your external model can be written in any .NET language such as Fortran, C++, C# or Visual Basic. Your function can then talk with internal solver data or link to external data at the same time. You can share your functions with others or sell them. Your Add-In variable list will appear within SIGMA/W so you don't need to compile variable values into your code.
Bars and Beams
Bars and beams are now better than ever. Beams and bars can exist in space on geometry lines and don't need to be tied to soil elements.
New Dynamic Deformation Model
There is a new model to handle post-earthquake deformation according to any constitutive relationship you feel is appropriate.
Advanced Staged Construction
Multiple analyses in a single file means you can run in-situ models and staged load deformation models in a single file. Perform detailed construction sequence modeling with moving boundary conditions.
Friction Based Interface Elements
Interface elements and a friction-based soil-structure interaction material model are now available. Specify different behavior on each side of the interface. The interface can cross over different soil strata.
Drained and Undrained in One Model
With enhanced soil models and analysis options you can include total stress drained soil regions with effective stress and pore-water pressure regions in the same analysis.
Stress Redistribution and C-Phi Reduction
A new stress-redistribution analysis option has been added. You can perform a C-Phi reduction, but more importantly, reduce C-Phi and then bring the stresses into SLOPE/W to check the factor of safety. Don't rely on non-convergence to give you a factor of safety. Bring excess earthquake generated pore-pressures from QUAKE/W into SIGMA/W so you can look at post-earthquake deformations. Review the San Fernando Dam detailed example discussion.
Collapse Surface
A collapse surface can now be defined for loose soils together with steady-state strengths. This information is very useful for flagging zones of potential liquefaction and zones with a sudden loss in shear strength.
Other Changes
  • A new circular opening mesh has been added, with boundary conditions applied on the opening edge. Add an interface element to simulate a tunnel liner.
  • A new submerged deposition analysis option has been added. Construct a tailings facility in a staged model.
  • Effective stress with pore-pressure changes has been enhanced. Do excavation with moving hydraulic boundary conditions.
  • Adaptive load stepping has been added to help with convergence issues in non-linear Elastic-Plastic models.
 

◎QUAKE/W 2007 Additional Enhancements

Non-Linear Model
A new effective stress non-linear model has been added. This new model uses accumulated volumetric strain to compute the development of excess pore-pressures.
Time Stepping Sequence
The time stepping integration sequence can now be related to the earthquake time history record. This ensures that the time steps are not greater than the time intervals in the input record.
G-Modulus Functions
The shear modulus G can now be defined by a generalized data point function dependent on the effective overburden stress. In addition, a G-modulus function can be selected from a range of sample functions for both granular and cohesive soils.
Collapse Surface
A collapse surface can now be defined for loose soils together with steady-state strengths. This information is very useful for flagging zones of potential liquefaction and zones with a sudden loss in shear strength.
Post-Earthquake Deformation
The excess pore-pressures and steady-state strengths can be used in a SIGMA/W stress-redistribution analysis to estimate permanent deformations that may arise due to the shaking.
Case History Examples
The San Fernando Dam case histories have been re-analyzed and documented in detail, to show what can be done with the new version.
Soil-Structure Interaction
The performance of beam and bar elements has been enhanced, making it possible to consider the effects of the structural stiffness on the ground response to earthquake shaking. This also makes it possible to examine the stress changes in tie-back anchors, for example, during an earthquake.
 

◎TEMP/W 2007 Additional Enhancements

Link to AIR/W and SEEP/W
AIR/W, which is tied to SEEP/W, can be linked with TEMP/W to account for convective heat transfer in moving air.
New Material Models
New material models have been added: full thermal, simplified thermal, and convective thermal with SEEP/W and AIR/W. There are now interface models for liners, barriers and thin insulation layers.
Add-In Functions
Define your own custom Add-In functions which can be applied to boundary conditions or materials. This feature, for example, will allow you to include your own climate boundary condition algorithm.
Multiple / Staged Analyses
Multiple analyses in a single file means you can have steady state and transient analyses in the same file. Change the mesh and re-solve the entire project in one step. Link analyses together to account for construction of tailings dams where soil is added and boundary conditions move with time.
Other Changes
  • Boundary conditions are preserved if you change the mesh.
  • New time stepping setup and results saving scheme.
  • New built-in sample soil property functions.
  • Improved thermosyphon boundary conditions.
 

◎CTRAN/W 2007 Additional Enhancements

Define Geometry in CTRAN/W
Now you can build your model in CTRAN/W and have it exist in the same project file as SEEP/W or VADOSE/W. If you change the geometry in CTRAN/W, it is automatically changed everywhere.  
Multiple Analyses in a Single File
Perform an advection/dispersion analysis in the same file as a particle tracking model. Results can be easily compared.
Add-in Functions and Boundary Conditions
Define your own custom Add-In functions which can be applied to boundary conditions or materials.
 

◎AIR/W 2007 NEW!

A New GeoStudio Product!
AIR/W is an exciting new product from GEO-SLOPE that completes the (ua-uw) matric suction stress state variable. The formulation is for density dependent compressible air flow, with or without thermal effects that can then be added by linking with TEMP/W. AIR/W is a plug-in license that requires SEEP/W.
Student Edition
AIR/W is now in the free Student Edition.
Analysis Possibilities
  • Soil vapor extraction.
  • Tunneling under air pressure.
  • Heat transfer due to air movement in frozen or unfrozen soils.
  • Reduced water infiltration due to air pressure blockage in dam cores or agricultural soils.
 

◎VADOSE/W 2007 Additional Enhancements

New! - VADOSE/W Basic
VADOSE/W Basic is now available as an affordable one-dimensional product. As the most advanced physically-based model on the market today, we think you will enjoy using the Basic Edition of VADOSE/W as an alternative to the HELP model.
Add-In Functions and Boundary Conditions
Define your own custom Add-In functions which can be applied to boundary conditions or materials. Include hysteresis, for example, or your own vegetation algorithm. Link the Add-In function to data that is solving simultaneously in Excel or another .NET framework program. Greatly Improved Results Graphing
VADOSE/W generates a great deal of result data. You can now set up and save graphs and plot various graph series at the same time. Compare water balance categories such as infiltration and base flow on the same chart.
New Solver
There is a new solver option to use the faster PARDISO system. The finite element equations are also now optimized for multi-processor computers.
Solve Coupled, Uncoupled or Isothermal
Choose the level of coupling you want in the model.
Advanced Meshing and Surface Layer Design
The meshing and surface layer design tools are vastly improved. The automatically generated default mesh will now suit most needs. New Student Edition
VADOSE/W one-dimensional analyses can now be done in the free Student Edition.
 

◎Other Enhancements

Project Templates
Create project templates to save personalized GeoStudio settings and model defaults.
Solvers
Multi-threaded solvers now take advantage of multiple processors in computers.
Improved Dynamic Sketch Text
Sketch text inserted fields can now be linked with results data; when you re-solve the model, the results are updated right on the screen.
View Results Information
Use the new View Results Information command in CONTOUR to multi-select nodes or gauss points to compare tabular data at different locations.
Other Changes
  • Meshing is now controlled by changing global settings or by putting restrictions on any geometry object.
  • When you change a key input parameter, the program will notify you that a solution is out of date and provide details as to what has changed.
  • All example files are shipped with the input files and detailed discussions.
  • All tutorials are now in movie format so you can watch, pause, try, and continue to build your models.
