Hi
I want to see the effect of gravity acceleration. I see different result in these situations: 1.DEFINE_SOURCE UDF 2. Without UDF (by enabling gravity option in FLUENT) Gravity Force by UDF= 679596.5 Gravity Force without UDF= 658589 Any idea please! -------------------------------------------------------------- #include "udf.h" DEFINE_SOURCE(z_mom_source, cell, cell_thread, dS, eqn) { real source; real time=CURRENT_TIME; source = C_R(cell,cell_thread) *9.81; dS[eqn] = 0; return source; } -------------------------------------------------------------- |
