Hi,
I have a problem with Fluent. I am running Ansys 13 under Scientific Linux 6.1. The problem is, when I want to create the mesh, the geometry cannot load in. I get an error message: “Tcp transport error”

Could you help me to solve this issue? I have very limited experience with Ansys.
Thank you very much in advance!
