Hi,
i write a udf code for define mass flow in mass flow inlet boundary which is in below,

begin_f_loop_int(f,t)
if PRINCIPAL_FACE_P(f,t)
{
count++;
}
end_f_loop_int(f,t)

begin_f_loop_int(f,t)
if PRINCIPAL_FACE_P(f,t)
{
F_AREA(c_sur,f,t);
inst_temp = F_T(f,t);
inst_rdot = aprexp * exp((-acte) / (ugc * inst_temp));
inst_mdot = frho * 2 * pi * NV_MAG(c_sur) * inst_rdot;
F_PROFILE(f,t,i) = count * inst_mdot;
}
end_f_loop_int(f,t)

after doing this code, i calculate mass flux in fluxes report on boundary in fluent, but the mass flux is n't summation of mass flux on all faces, that is only mass flux for a face.
please guide me,
thanks.
