Meshing

Perform Tetra meshing for the enclosed volumes.

You will create tetra mesh or volume mesh using the enclosed volume assemblies created in the Pre Meshing operations.

  1. From Define group, select Tetra > Create.
    Figure 1.
    A guide bar will appear.
  2. On the guide bar, click to define tetra mesh options.
    Figure 2.
  3. Change Average Size value to 500.
  4. From the model browser, isolate Volume_07 assembly.
    This isolates the respective enclosed volume and its components.
  5. Select the horizon pair (top and bottom) and the wall component for Components selection option.
  6. Click Mesh.
    This will create tetra mesh within the enclosed volume and a vol001 component will be created and listed in the model browser.

    Note: If the mesh creation fails, it is likely that the volume is not enclosed and contains free edges. You can fix this by (re)performing pre-meshing operations.
  7. Repeat the above steps to mesh all the volumes in the model.
    Note: You can also select all the components in the model and the tool will create 3D mesh for each of the volumes it finds.

Fault Properties

Create contacts between fault planes and volume meshes.

Using the Fault Properties tool, you will define contacts between the fault planes and the volume meshes.To create contacts, you will have to preview and equivalence any free nodes.
  1. From the Fix group, select Tools Ribbon.
    From Tools Ribbon, select Free Edges.
    Figure 3.
    Default HyperMesh Edges panel will appear.
  2. Select all the components in the model and click preview equiv.
    You can preview and equivalence free nodes, if any.

Create Contacts

  1. From Define group, select Fault Properties.
    Figure 4.
    A guide bar will appear.
  2. Select Offset Slave: Offset Master from the contact type list.
  3. Select all the faults in the model.
  4. Click Create.
    Once the contact creation is completed, contact groups will be listed in the Model browser.
