FACE MACROS FOR PRESSURE

Hello All
I am trying to solve for a compressible flow with pressure inlet BC The user manual says that total pressure should be input in the inlet BC for pressure in the case of compressible flows My inlet velocity varies with time and hence I plan to write a UDF to define total pressure BC at inlet. For this I am doing the following P_BC = P_static + 0.5 * density * velocity*velocity T_BC = T_static + velocity * velocity / Cp To access the pressure and temperature on face of boundary the manual gives the macro F_P(f,t) and F_T(f,t) --- Is this pressure and temperature outputted by solver to UDF static pressure and temperature or total pressure and temperature? Because this affects the way i formulate my formula above Please let me know Thank you Sandilya |

I am pretty sure (same like you are pretty) that F_P(f,t) is macro accessing static pressure.
Ħque lo pases bien! |

Yep, F_P is for static pressure (relative to operating pressure)
