Temperature divergence
 

Hi all,

I am trying to simulate a train travelling through a tunnel at M = 0.88 but keep getting the "Divergence detected in AMG Solver:TEMPERATURE" error.

I suppose it has to do with my boundary conditions. I've imposed walls moving at 300 m/s in x-direction, a total pressure / temperature inlet and static pressure outlet. Tried it with both SA and k-eps models.

Does someone by chance know what could cause the error or knows of any place where I can find examples / tutorials of similar problems?

Cheers!
