UDF for species-mass-fraction gradient at outlet
Hi, I am modeling species transport in high temp in steady state. In this model I have used the species CO,CO2,H,H2....etc. I want to set the gradient of the species-mass fraction =0.0 instead of mass-fraction = 0.0 at the pressure outlet boundary for species. For this i have written an UDF which is given below.
#include "udf.h" DEFINE_SOURCE(species_grad,cell,thread,dS,eqn) { float source=0.0; begin_c_loop(cell, thread) { C_YI_G(cell,thread,1)[0]=0.; source=C_YI_G(cell,thread,1)[0]; /*dS[eqn]=0.;*/ } end_c_loop(cell,thread) return source; } After compiling the file when I am trying to HOOK it the UDF file is not displaying in the species-mass-fraction at the pressure outlet . But I check the UDF file is available at the Boundary Condtion-Fluid-Source term for species. Anybody can help to solve this problem? I will be greatful to you for your help. Thanking you. sisir |
