I have created a UDS which runs nicely, however I want to specify the flux at the walls of the aircraft wing to be the same as pressure flux. I used the following code:


DEFINE_PROFILE(UDSP, t, i)
{
real x[ND_ND]; /* this will hold the position vector */
real y, h;
face_t f;
real A[ND_ND];

begin_f_loop(f,t)
{
F_CENTROID(x, f, t);
F_AREA(A,f,t);
F_PROFILE(f, t, i) = A[0]*C_P_G(f,t)[0]+A[1]*C_P_G(f,t)[1]+A[2]*C_P_G(f,t)[2];
}
end_f_loop(f, t)
}



however I keep getting an error. Any help would be appreciated
