Good time,
Is it possible to define 2 user define function in one UDF?
I have check the UDF manual and as for I understand in C_UDSI(c,t,P1), P1 is an integer having some value like 1,2,3......

I means in the UDS macro, p1 is the name or index of UDS.

so is it possible to use C_USDI(c, t, 1) is a UDS, named "1", and C_USDI(c, t, 2) is a UDS, named "2"
will this idea be correct?

DEFINE_SOURCE(energy_source, c, t, dS, eqn)
{
dS[eqn] = 0;
return -abs_coeff*(4.*SIGMA_SBC*pow(C_T(c,t),4.) - C_UDSI(c,t,P1)); }


Thanks in advance.
