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 ConvergenceThe 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.
Watch a movie showing the new docking window support in GeoStudio:
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.
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.
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.
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 transfer your activation to that computer.
Network licenses are now controlled using a new license server with a web-based monitoring interface. Network licenses can be "re-hosted" onto new server hardware using an included activation utility.
Save Files in GeoStudio 2012 or 2007 FormatFiles 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 EnhancementsMany 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 FixesMany bug fixes have been made throughout all products to improve performance and stability.
