Set a specific inlet pressure using a velocity inlet boundary

  Hello Everyone,
  I am attempting to simulate a hydrogen leak into an air-filled environment. I know that the hydrogen enters the environment at 950 m/s and that the storage pressure is 350 bar.
  By setting a velocity inlet boundary, I can set the inlet velocity to 950 m/s, but how can I set the pressure at which the hydrogen enters the environment (i.e., the storage pressure)?
  I have tried different methods, but none seem to work.
  
  Thank you. ????

  Try using the "Supersonic/Initial Gauge Pressure" option.
