Pre Processing

Use the GeoD-Pre tool to import, perform pre modeling operations, setup loadcases and export the run-ready model.

The Pre-processing is available on HyperWorks and HyperMesh Desktop. This module allows you to perform the following main operations:

  • Import geological data, models and geometries from existing earth models and point clouds.
  • Perform clean-up operations such as:
    • Remeshing and smoothing of surfaces (horizons, faults etcetera);
    • Find gaps or holes in surfaces and stitch them.
  • One-time definition of the geological (stratigraphic) hierarchy for subsequent autonomous operations
  • Define model domain extents and build boundaries (sidewalls) to enclose stratigraphic and/or fault block volumes.
  • Generate solid elements (tetra/hexa/penta/pyramid) for the model domain.
  • Export solid meshed model into user selected solver format with required cards and flags.
Note:
  • The Pre-Processing supports the following file format for import*:
    • Zmap- *.zmap, *.dat
    • TSurf- *.ts
    • Solid Model files-*.sm
    • TSolid files-*.so
    • LAS- *.las
    • Point/Node Cloud- *.csv
    • STL- *.stl
    • DXF- *.dxf
  • It supports automated one click tetra mesh generation from a water tight volumetric mesh;
  • It exports TSolid, Solid Model and Abaqus files in addition to all file formats available in core Hypermesh;
  • TSolid format exports 3D tetra element types only

Launching GeoD-Pre

  1. Start HyperWorks from HyperWorks 2022 installation.
  2. From HyperWorks main menu bar, select Directors > GeoD.
  3. Click GeoD from the main menu bar.
    The GeoD Pre Processing ribbon will appear.
