Kay Guest Posts: n/a	Hi, everybody. Who can explain the 5 kind of pressuresperating pressure,gauge pressure,static pressure,stagnation pressure and total pressure,which always confuse me. I'm simulating the flow field in a firebox,c3h8+5o2---3co2+4h2o.The inlet pressure of c3h8 is 0.4MPa,0.5MPa for o2. Now, how to set the pressure boundary conditions? In the pressure inlet dialog box,how to set "Gauge Total Pressure" and "Supersonic /Initial Gauge Pressure"? And what's connection of those pressures with the operating pressure? Thanks very much. Kay
