Suggestions for best software to do the mesh
 

Hi all,

I am evaluating thermal comfort of animals inside a big room. Basically, the domain is a big room with inlets, exhaust fans as outlets, and animals inside the room. I tried making the mesh in Salome using Netgen (1D, 2D, 3D) but I am not confident with the results. Is there anyone here who can suggest for the best software to prepare the mesh of this kind?

Thanks,
