manu Guest Posts: n/a	I'm writing a UDF in which I need to access the average value of the pressure on a compressor exit area (that have been calculated with 3D simulation). This so-called "area mass average" value is define as: sum(p_iA_i_m_i)/sum(A_i*m_i) where p_i is the pressure, A_i the area and m_i the mass flow in each cell of the exit face. I found the function "F_P(f,t)" that records the pressure in each cell of the face but not the average value. Does anybody knows how to compute this average then? Thanks Manu
