6.3.5 ICEM CFD Mesh Files

You can use ICEM CFD to create structured meshes in FLUENT 4 format and unstructured meshes in RAMPANT format.

• To import a FLUENT 4 mesh, follow the instructions in Section  6.3.13.

• To import a RAMPANT mesh, use the File/Read/Mesh... menu item, as described in Section  4.2.

The current ANSYS FLUENT format is the same as the RAMPANT format, not the FLUENT 4 format. After reading a triangular or tetrahedral ICEM CFD volume mesh, perform smoothing and swapping (as described in Section  27.13) to improve its quality.
