When exporting to OpenFOAM, cell and face data can be exported as Sets, Zones, SetsAndZones, or not at all. The PointPrecision attribute can also be set via the Set Solver Attributes panel shown below.
As required by OpenFOAM, all 2D grids are thickened (extruded) to a 1-cell-deep 3D grid during CAE export. The SideBCExport attribute controls how boundary conditions are applied to the base (original) domains and to the top domains of the thickened grid. The available options are:
Option | Description |
---|---|
Unspecified | No boundary conditions are applied. |
Single (default) | Both base and top boundary faces are placed in a single boundary condition named BaseAndTop with type Empty. |
BaseTop | The base boundary faces are placed in a boundary condition named Base with type Empty. On the other hand, the top boundary faces are placed in a boundary condition named Top with type Empty. |
Multiple | The base and top boundary faces are placed in a boundary conditions of type empty named <VCName>-base and <VCName>-top respectively. <VCName> denotes the name of the volume condition assigned to the original 2D grid. |
The Thickness attribute controls the depth of the thickened grid; its default value is 0.0. Note that a Thickness of 0.0 will trigger an auto-compute functionality that will compute the optimal thickness for the 2D grid being exported.

Keep in mind that OpenFOAM does not support what is considered to be standard volume conditions. That being said, Fidelity Pointwise has defined a set of "special" OpenFOAM volume conditions that can be used to define different variations of face/cell sets and face/cell zones to be exported.
When the current CAE solver is OpenFOAM, you can define collections of faces in the CAE, Set Volume Conditions panel and use the volume condition Type options to define which cells and faces should be exported via the File, Export, CAE command. The table below, presents information regarding the specific meaning of each Fidelity Pointwise defined OpenFOAM volume condition Type.
Type | Description |
---|---|
volumeToFace | All faces are exported |
interiorToFace | Only interior faces are exported |
boundaryToFace | Only boundary faces are exported |
interiorToFace+boundaryToFace | Interior and boundary faces are exported separately |
volumeToCell | All cells are exported |
volumeToCell+volumeToFace | All cells and faces are exported |
volumeToCell+interiorToFace | All cells and interior faces are exported |
volumeToCell+boundaryToFace | All cells and boundary faces are exported |
volumeToCell+interiorToFace+boundaryToFace | All cells and interior and boundary faces are exported separately |
