exponential source term
Hi all I define source term to uds function in fluent.the source term is function of uds variable. my udf is :

DEFINE_SOURCE(s_auds,c,t,dS,eqn) { real source; source =exp(C_UDSI(c,t,0)); dS[eqn] = exp(C_UDSI(c,t,0)); return source; }

however it dont converg, why it divergent ? thanks all. Pourak
