Hi to everybody,

I am new in Ansys. I wanted to ask two questions:

• If I chose pressure-far-field for two horizontal sides (upper and lower boundaries of the domain, in Fluent they are called free2) I cannot put Mach Number equal to zero: "Error at Node 0: Mach number at Pressure Far-Field boundary should not be set to zero.";
  
  
  
  •    Why I cannot put a Mach number of 0?
  
  
  
  


• If I put a very low number for Mach number I get the result in the picture attached, which is technically wrong;
  
  
  
  •    Do you know I get this kind of strange results?
  
  
  
  

 

 

Thank you.

Linda
