  Hi,
  
  Does anyone know hoe to plot the Mach Number Contor when using Pressure Based Solver? The ANYS Help provides the following image
  
  However, there is no such option of Mach Number available within the tab
  
  Thanks,

  I'm guessing that air density is constant. Mach Number is available for compressible materials. Otherwise use a Custom Field Function and divide velocity by the speed of sound to show Mach Number for your system.

  Density is approximately constant (Incompressible ideal gas) Where can I find custom field function?
  
  Thanks,
