Description
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.
The solver attributes for OpenFOAM include cell and face export format and point precision.
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.
OpenFOAM volume conditions
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.
Fidelity Pointwise has defined special OpenFOAM volume conditions that allow you to define which cells and faces should be exported via
the
