Combine Analyses in a Single, Integrated Project

The integrated GeoStudio software suite allows you to combine multiple analyses using different products into a single modelling project. You can then use the results from one analysis as the starting conditions for another one. New analyses can be easily created by cloning an existing analysis and adjusting its properties. When you are ready to analyze the model, GeoStudio solves the analyses in the appropriate order, taking advantage of parallel processing.

This unique and powerful feature greatly expands the types of problems you can analyze. Use this approach to model construction sequences, establish initial conditions, perform sensitivity analyses, model complex time sequences, or simply decompose a complex problem into a number of smaller, more manageable analyses.

Included with the purchase of any GeoStudio single product or bundle is a free GeoStudio Basic license. Analyses created with a Geostudio Basic license can be included in the same file as the full-featured GeoStudio analysis, further unlocking the power of integration.

Multi-view Modeling Environment

Docking windows in GeoStudio 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 status bar provides both view information and quick access to commands such as zooming, and a progress bar during lengthy operations such as solving.

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.

Define Geometry using Drawing Tools or by Importing CAD files

Defining the geometry of the physical system is usually the first step in a numerical analysis. GeoStudio provides all the tools necessary to define the model domain including coordinate import, copy-paste geometric items, length and angle feedback, region merge, region split, and direct keyboard entry of coordinates, lengths, and angles. Otho-snapping to horizontal and vertical directions can be used to facilitate geometry definition. 

AutoCAD DWG or DXF files can be imported directly into GeoStudio for the definition of domain geometry. In addition, image files can be imported, scaled, and the region geometry drawn directly over top.

Apply Materials to the Domain for each Analysis

Once the domain regions are defined, you can apply material properties to each of the regions individually or as a group. Applying materials to individual regions allows you to model different materials in different analyses. You can also remove portions of the domain in different analysis by not applying materials to these regions; this allows each analysis to consider new regions added to the domain in stages.

Material properties can also be applied globally to all analyses in the project or to individual analyses. Applying materials across all analyses makes it easy to change your material definition when you are using many analyses in a single project.

Define Soil and Rock Material Models using Flexible, Generalized Functions

GeoStudio makes broad use of generalized functions for material property and boundary condition definition. Enter parameters for pre-defined functions, or create your own functions using your own data. You can even write your own Add-In functions or constitutive models to compute material property values while the analysis is being solved, allowing you to extend GeoStudio in nearly infinite ways.

Automated Finite Element Meshing of the Geometry

When materials are applied to the domain regions in a finite element analysis, a default finite element mesh is automatically generated. While in many cases the default mesh is adequate, you can adjust the mesh either globally or by applying constraints to specific locations. This allows you to keep a coarse mesh in most regions while applying a fine mesh within particular portions of the domain that may have highly nonlinear properties or boundary conditions. As you adjust the local constraints, GeoStudio re-generates the mesh over the entire domain, while still preserving your existing model definition.

Use the Keyboard to Enter Coordinates While Drawing Objects

Coordinates can be entered using your keyboard while any drawing command is active. This keyboard input option allows you to enter Point coordinates using the x-y coordinates, length and angle input, offset lengths in the x-y directions, or simply the Point numbers. A tooltip displays this information while drawing points using drawing commands such as Draw Regions. Undo and Redo is supported while using the drawing commands.

Integrate your own Code using GeoStudio Add-Ins

You can write supplemental programs called Add-Ins that will be called by the GeoStudio Solver when it solves your analyses. A Function Add-In takes the place of a function defined in GeoStudio, and offers the flexibility of computing function results that vary dynamically based on the current mesh state.

GeoStudio provides an Add-In API (“application programming interface”) that your Add-In can use to query parameter values while GeoStudio is solving the analysis. You can use these values to return the required function parameter value. You can also use the Add-In API to write out your own custom parameters for later viewing using the regular GeoStudio result visualization features.

Each Add-In function is an object that GeoStudio associates with either a node or gauss point, depending on the kind of function that references the Add-In. Boundary condition functions are assigned at nodes, and Material property functions at gauss points. There are many instances of the function object created when the solver runs, one for each node or gauss point where the function is used.

In SLOPE/W, an Add-In can be written to access data that exists at the base of a slice where that slice contacts the failure plane (or slip circle).
