1. What is the differnce b/w the total pressure and the supersonic/initial guage pressure?

2. From where I can get the supersonic/initial guage pressure?

supersonic/initial gauge pressure is only used during initialization to push flow in correct direction. Later it doesn't inlfuence on sollution. Corresponding to the value of this pressure: i usually set in a little bit larger that outlet pressure. For example, if you set outl. stat. press. to 100kPa the initial pressure set 105kPa.
