I'm writing an UDF and trying to access the pressure on a wall by using macro F_P() and this works fine in pressure based solver. But as far as I know, F_P() can not be used in density based solver. Is there any macro that can replace F_P() in density based solver? or other way to access wall face pressure?

Hi! Thank you for your reply. I tried to use pressure and the gradient of pressure on cell center to extrapolate pressure on face center. Macro C_P is available in density based solver. But I can’t access the gradient of pressure. I also tried to use C_R_G and C_T_G to solve pressure gradient with ideal gas equation but received an error message too. Do you have any recommended extrapolation method? Or where I could find a reference for pressure extrapolation in fluent?
