hamid1 is on a distinguished road

i want to calculate average pressure at the boundary,
the code is as follow?


face_t f;
real NV_VEC (A);
F_AREA (A,f,thread);
P= force/(area of cross section);
VF = QF/(area of cross section);

my question is for finding average pressure at the boundary which of the following is correct?

F_AREA (A,f,thread);
pressure = force/(area of cross section)


Pressure= F_P(f,thread);


another question is can i use minus value in velocity inlet?

thanks alot for ur helps
