DavidB New Member Join Date: May 2013 Posts: 2 Rep Power: 0	Hi everyones, I'm simulating a model of a car with air intake (pressure outlet with fixed mass flow rate) in the front part and nozzle(mass flow inlet)In the rear parte, for understanding the effect of the flow of that nozzle on the car drag. I've some problem with the estimation of the pressures forces because I don't know if I have to set che REFERENCE PRESSURE in reference values to zero or to 101325 Pa. I use operative pressure of 101325 Pa and the gauge pressure in the other boundary condictions. Thank you in advance.
