ANSYS Fluent (legacy) supports 2D and 3D grids of all cell types that can be created in Fidelity Pointwise. This exporter is used by V17.0 and earlier versions of Pointwise that is compatible with Gridgen's Fluent exporter.


Caution: The presence of pole connectors and pole domains in structured blocks can result in degenerate hexahedral cells when exporting to an unstructured CAE format. Please refer to the Collapsed Cell Types section of this User Manual for more information on which structured topologies result in unsupported cell types.

Unlike ANSYS Fluent that groups boundary conditions by volume conditions, this exporter groups boundary conditions by which block they belong to when volume condition is not specified.

In the figure shown below, for example, two boundaries with the BC name "Outflow" are associated with "Block-A" and "Block-B" respectively. If the volume condition is left "Unspecified" for these two blocks, that results in two zones upon export. Likewise, two zones will be created for the three "Wall" boundary conditions.

However, one zone will be created for "Outflow" or "Wall" boundary condition if ANSYS Fluent is used.

Fluent BC example
ANSYS Fluent (v15) handles unspecified volume conditions different than ANSYS Fluent.
