Hello, every one!
I want to add an addition term to the source term of the temperature field ,and my UDF file is:
DEFINE_SOURCE(Energy_source, c, t, dS, eqn)
{
real x[ND_ND];
real source;
real Dmu; //turbulent viscosity derivative
C_CENTROID(x,c,t);
Dmu=2*(C_K(c,t)/C_D(c,t))*C_K_G(c,t)[1]-C_K(c,t)*C_K(c,t)/(C_D(c,t)*C_D(c,t))*C_D_G(c,t)[1]);
source =-g/Prt*C_R(c,t)*Cmu*Dmu;
dS[eqn] =0;
return source;
}

However, when I run my calculation, an error warning appears:
"
Error: received a fatal signal (Segmentation fault).
Error Object: #f
"

You are missing definition of g and prt in the code

anyone know how this problem solve?
it's from not defining C_T_G or... but how we do this?
thanks
