Geomechanics Director

Altair's Geomechanics Director (GeoD) is a solver agnostic environment for building and analyzing geo-scientific simulation. GeoD simplifies the model building and result interpretation process for the geoscientist. It increases efficiency and accelerates the creation of geoscience models, thereby allowing analysts to invest their time in interpreting and decision-making, rather than time consuming model building process. GeoD has two modules, namely GeoD-Pre and GeoD-Post.

GeoD-Pre provides the following high-level functionalities:
  • Import geometries like tsurface, tsolid, etc.
  • Clean up and fix bad geometries.
  • Intersect horizons and faults.
  • Create and organize enclosed elements.
  • Generate meshes or solid elements including tetra, hexa, penta, etcetera..
  • Export meshed model into Solid Model and solver formats with configuration for submission to simulator of choice.
GeoD-Post provides the following functionalities:
  • Effective stress calculation and stress-based metrics.
  • Capability to derive new results that the conventional solver cannot output.
  • Ability to map results from 3D to 3D, 2D and 1D elements.
  • XY plotting for variations of stresses, pore pressure and other results on the wells.
  • Automated capability to export scalar, vector and tensor results to ASCII format.
  • Ability to store and propagate results in the form of h3d file.

HyperWorks Compatibility

Certified on HyperWorks 2021.1.

What's New

Ribbon
The ribbon is re-organized to give a cleaner user experience, with the tools rearranged in logical groups that follow the workflow. The sub- ribbons are removed from the main ribbon and added as pages at the top, renamed as gTools, gGeometry, gMesh, and gSetup.
Figure 1. GeoD ribbon
The following tools are renamed as:
  • GeoD Model to Classify.
  • Walls to Enclose.
  • Enclose Volumes to Organize.
  • Contacts to Fault Properties
Import
The Create mesh from lines feature is added to the GeoD – Import dialog.
Figure 2. GeoD- Import dialog
The Average mesh size specifies the expected output mesh size while generating from lines.
Classify: Hierarchical part view
Now you can expand or collapse different entities at the same time and expand or collapse all.
Figure 3. Classify Model and Hierarchical Part view
Faults
Faults intersections are now performed whenever the fault mesh is classified in the same component; different components, same part; different components, different parts.
The stitch gaps feature is added to the Faults tool. You can choose if you want to enable the stitch gaps functionality and specify the tolerance of the gaps to stitch.
Figure 4. Options for Faults tool
Enclose
The Define fault blocks feature is added to the Enclose tool. You can enable this feature in the options menu when using the Auto Enclose and Enclose by Rectangle options.
Note: This can be enabled when using the Auto Enclose and Enclose by Rectangle options
Figure 5. Options for Enclose tool
Perforation Tool
The Perforation tool is added in this version. This tool creates a Hex mesh perforation model according to the selected parameters from the pre-defined options. You can find the perforation tool by expanding the mesh-type icons.

Documentation
The Help icon has been removed from the Ribbon, you can access Help documentation when pressing the F1 key.
The online help contains the documentation on the features of the Pre and Post-processing aspects of GeoD. Additionally, tutorials are also available in the online help. In case any help is required please send your questions to our support lines via Altair Community.

Known Limitations

  • The user might find mesh intersections on some of the smallest models created by the Perforation tool.
  • In GeoD Post, the status or user message is not available during the mapping process.

Bug Fixes

All issues reported in previous versions are fixed in this version.
