  Hi,
  
  I would like to simulate the thermal behavior (in ansys aim) of a body (e.g cube) in vacuum. Can someone tell me if the following is an advisable approach?
  - define only radiation boundary in simple thermal simulation template
  or should i incorporate a fluid simulation and incorporate low pressure boundary conditions to it?
  
  Appreciate your help
  
  Thanks

  If it's radiation transfer only I'd suggest using Mechanical. Why use a CFD code if there aren't any fluids?
