Convert GMSH .msh to ANSYS .msh

[ghost]

Hello,

Using the following command ./feconv -gm input_GMSH.msh output_ANSYS.msh results in the program running for very long but does not output anything. This is in ubuntu 20.04.

Thanks,

Peter

Hi, there is a not stressed enough hole in the documentation: you cannot directly convert from one MSH format to another MSH one. You have to use a third format instead. For example: ./feconv -gm input_GMSH.msh tmp.unv ./feconv tmp.unv output_ANSYS.msh I will try to clarify this point in the documentation.

Ok thanks. I will try to convert like that. How much should it take for a 500MB mesh?
Thanks,
Peter

Hi, I cannot give you a realistic prediction: it depends on your machine, the format (ANSYS is quite slow since a surface-volume conversion), the compiler (ifort is faster than gfortran), ... It would be helpful to make a preliminary test with a smaller mesh in order to be sure that there is no problem.

Helo,

I have reduced the size of the mesh which is a 3D unstructured mesh. However, I have not been able to convert it to a .unv format to convert that to ANSYS .msh. However, I have tried some of the examples and they do work. This is on linux using gfortran. The mesh is created in GMSH and saved in ASCII Version 2 format. Any ideas on what I can try?

Hi, so the step that is failing is the first one: *feconv -gm mesh.msh mesh.unv*, right? Is any warning or error in the output? The format is correct (ASCII Version 2). Maybe, it could be a problem with non-consecutive numbering, but it is difficult to say more without knowing the mesh. If you can send me the mesh, I can give you a better answer.
