Hello all,

I have created an CAD-file using Freecad, I want to create the mesh using snappyHexMesh but run the case using Fluent. The problem is that I require two surfaces in order to add two surface heat sources to the mesh.I haven´t been able to create them using Freecad+snappyHexMesh yet. I create the patches with the "surfaceAutoPatch"-command, with which - as far as I know - I can´t create two patches on one surface. Is there another way? Supposing that everything works fine, how can I export the created "cell zones" and patch-data to a Fluent .msh file?

Supposing that the mentioned alternative doesn´t work, could I add surfaces to the existing CAD-file in order to set them as surface heat sources in Ansys Meshing or in Fluent?

I would really appreciate your help.

Thank you very much in advance.
