Problem:
I am trying to convert one of my fluent 2021 R1 generated mesh to OpenFOAM using fluentMeshToFoam/fluent3DMeshToFoam; however, I think due to the change in fluent 2021 .msh file format, I am not able to convert to OpenFoam format. I am able to convert the older Ansys version (19.2) to OpenFoam mesh. Is there a way to convert the fluent 2021 R1 mesh to OpenFOAM?? |

I also get the problem.
To solve it I used star-ccm. In the soft, I import .msh, and then I export the mesh as .ccm. After that, I used the command ccmToFoam. This is a way to solve this problem. If you are not an user of star-ccm, how about using only tetra mesh? I could convert it by fluentToFoam. |

Dear Kensuke tanaka,
Thank you for your reply. I have checked for hex and poly mesh but not tetra mesh. I will check, whether I am getting the same error or not as we do not have star-ccm. |

I am using the same version of ANSYS. I have no problem with converting Flunet msh into OF. The mesh file must be written in ASCII format, which is not the default option in Fluent. Before you export msh file, you need to change format of input file (*.msh) in Options card in Fluent. You may find some reference tutorial from Youtube. |

Thank you for your reply. I have written *.msh file in ASCII format. However, as pointed by Kensuke Tanaka, for inbuild fluent generated meshes, the fluentMeshToFoam/fluent3DMeshToFoam are only working for the tet mesh, not for hex/polyhedral mesh. -Best, Parth |
