Assigning Moving Mass Boundary Condition

  To all the Masters of Ansys,
  
  Does anyone know if there is a way to apply a moving mass boundary condition to a 3D geometry? Recently, I was informed by someone that you can specify a moving mass ( additional force function) to a surface of a 3D geometry in steady state thermal analysis to simulate a mass flow rate across a surface to simulate heat flux out of that surface. The only thing I could find in the documentations that talks about this boundary condition describes you can only specify a mass flow rate boundary condition on wire body, line body and beam.
  
  The purpose is to simulate mass flow rate without the utilization of Fluent or CFD.
  
  Any references or sources that can point me to the right direction would be greatly appreciated.
  
  Best Regards,
  
  Peter

  Here is a post with an example of a mass flow rate on a line body.

  Peter,
  
  Thank you very much for your response. I see the way your simulation was setup is to map the line body with the convection boundary condition. What I want to know is how is this being calculated within the software? Is there a reference location where I can find all the formulations for calculations within Ansys?
  
  Best Regards,
