I am using Ansys 2023 R1. I have created a mesh using Fluent Meshing and I want to export the mesh in .msh format for import into CFX. However, Fluent Meshing only offers export options in .msh.h5 or .msh.gz formats, which CFX can not read. Is there a way to export the mesh directly as a .msh file in Fluent meshing? If not, how can I import the mesh generated by Fluent meshing into CFX?

Hi Farshid,

Starting 2022 R1, CFX supports msh.h5 files. However, the element types supported by the CFX solver are tetrahedral, pyramidal, prismatic, and hexahedral. So Fluent meshing by default produces Polyhedral element type which is not supported. So if this is the case, you have to go and edit the fill type and make it tetrahedral by going to the 'Generate volume mesh' section. By changing the Solver to CFX, you will have two Fill options available, Tetrahedral and Hexahedral.

After that save this mesh file, and then import this in CFX pre. In the Import mesh dialogue box, choose the File type as Fluent.
