Hi Ramu,

What material did you use? If you used a compressible material, such as "Air Ideal Gas", the solver will return the Mach Number. If you ran with Air at STP or another incompressible material, Mach Number will not be calculated.

Are you running a transient and loading a .trn file? In that case you may not have chosen to write the Mach Number to the .trn file. Otherwise, Mach Number will already be there, assuming you have a compressible fluid as Robin has suggested. Is you Steam material compressible (I know that steam is compressible, but check the actual material definition you are using).
