HI, guys.
I want to solve this UDS in fluent.
dHL/dt=source_term
Is it possible for me to solve this equation in a steady solution?
My case is a steady case.
Is the following UDF right for my case?
#include "udf.h"
DEFINE_UDS_UNSTEADY(HI_uds_unsteady, c,t,i,apu,su) /
{
real physical_dt,phi_old;
physical_dt = 0.01;
*apu = -1./ physical_dt;
phi_old = C_STORAGE_R(c,t,SV_UDSI_M1(i));
*su = phi_old/physical_dt;

}


thanks a lot
