Hexa Mesh Generation with Blocking

The process to generate a Hexa mesh is outlined below, and described in detail in the following sections.

  1. Import a geometry file using any of the direct, indirect, or faceted data interfaces.

  2. Interactively define the block model through split, merge, Ogrid definition, edge/face modifications, and vertex movements.

  3. Check the block quality to ensure that the block model meets specified quality thresholds.

  4. Assign edge meshing parameters—such as maximum element size and initial element height at the boundaries—and set the expansion ratios.

  5. Generate the mesh with or without projection parameters specified.

  6. Check the mesh quality to ensure that specified mesh quality criteria are met.

  7. Write output files to the desired solvers.

If necessary, you can always return to previous steps to manipulate the blocking if the mesh quality does not meet the specified threshold or if the mesh does not capture certain geometry features. The blocking can be saved at any time, allowing you to return to previous block topologies.

Additionally, at any point in this process, you can generate the mesh with various projection schemes such as full face projection, edge projection, point projection or no projection at all.


Note:  In the case of no projection, the mesh will be generated on the faces of the block model and may be used to quickly determine if the current blocking strategy is adequate or if it must be modified.
