The forum OpenFOAM Other Meshers: ICEM, Star, Ansys, Pointwise, GridPro, Ansa, ... was closed near the end of April 2019 and replaced with prefixes on the main OpenFOAM Meshing forum. The following is my original post that has been restructured a bit in function of the new forum structure. For more details about the new forum structure, read this thread: Map of this Meshing (sub-)Forum

It's expected that with this new forum structure, it is also used to discussing issues with generating and converting meshes that are generated with commercial and closed source meshers that work independently from OpenFOAM. Nonetheless:

• The objective is mostly to discuss how to generate and/or convert meshes that are usable by OpenFOAM, to be discussed within the prefix [Commercial meshers].
• As for using each software, please refer to their respective forums and commercial support.

Reference links for each software:

• Ansa
  • The meshes generated with BETA CAE Systems S.A products can be exported directly to OpenFOAM format.
  • Relevant forum here at CFD-Online: ANSA
• ANSYS Meshing, DesignModeler, ICEM CFD, TGrid, GAMBIT and other meshing and geometry tools from ANSYS
  • The meshes generated with ANSYS products have to be converted to OpenFOAM's mesh format. Conversion instructions are provided in the following wiki pages (most descriptions copied from this wiki page: Main_OFUtilities):
    • ansysToFoam - Converts an ANSYS input mesh file, exported from I-DEAS, to OpenFOAM format (formerly called ideasToFoam).
    • cfx4ToFoam - Converts a CFX 4 mesh to OpenFOAM format.
    • fluent3DMeshToFoam - Converts a Fluent mesh (in ASCII format) to OpenFOAM format.
    • fluentMeshToFoam - Converts a Fluent mesh (in ASCII format) to OpenFOAM format including multiple region and region boundary.
    • foamMeshToFluent - Writes out the OpenFOAM mesh in Fluent mesh format.
    • gambitToFoam - Converts a GAMBIT mesh to OpenFOAM format.
    • Import a fluent mesh with interfaces
    • Importing a FLUENT mesh with internal walls
  • Relevant forum here at CFD-Online: ANSYS Meshing & Geometry
• CD-adapco: Star-CD and Star-CCM+
  • The meshes generated with CD-adapco products have to be converted to OpenFOAM's mesh format. Conversion instructions are provided in the following wiki pages (most descriptions copied from this wiki page: Main_OFUtilities):
    • ccm26ToFoam - Converts a STAR-CCM mesh to OpenFOAM format.
    • foamToStarMesh - Reads an OpenFOAM mesh and writes it in PROSTAR (v4) format.
    • star3ToFoam - Converts a STAR-CD (v3) PROSTAR mesh into OpenFOAM format.
    • star4ToFoam - Converts a STAR-CD (v4) PROSTAR mesh into OpenFOAM format.
  • Relevant forum here at CFD-Online: CD-adapco
• GridPro
  • The meshes generated with Program Development Company products have to be converted to OpenFOAM format. There is no specific exporter in OpenFOAM, but there is one available here: GridPro to OpenFOAM converter
  • Relevant forum here at CFD-Online:GridPro
• Pointwise
  • The meshes generated with Pointwise products can be exported directly to OpenFOAM format.
  • Relevant forum here at CFD-Online: Pointwise & Gridgen
