[Commercial meshers] Mesh conversion .gtm to OpenFOAM

ansab · December 1, 2016, 11:35

Hello respected members,

I have a mesh created using ANSYS Turbogrid and I can save it in either .cgns or .gtm format.

As I want to convert this mesh now in OpenFOAM to perform simulation in OpenFOAM, can anybody guide me in this regard. Can we convert .gtm files using CFX4toFOAM command ? or is there any way to convert .cgns files into OpenFOAM format. Please help me I am stuck.

Any kind of help is appreciated.

Thanks in Advance

Hello,

In my personal experience, there are some cases you could to that trick FluentToFoam etc. However, openFoam excepts files that are extruded by a factor of one, which I don't know in your case you have that or not. Since you will be using OpenFoam, I would suggest to use one of those open-source mesh tools. I personally have a year experience with gmsh and feel that you can switch your mesh into it easily. I can help you with that if you want.

Cheers,,
