hi there
im new to udf , im trying to learn how to use define source ? when i Intereprete this udf fluent exits with an error, i was wondering what is causing this?

#include "udf.h"
#include "math.h"
DEFINE_SOURCE(energy_source,c,t,dS,eqn)
{
real x[ND_ND];
real con, source;
C_CENTROID(x,c,t);
con = 50*exp(1/((x[1]*x[1])*(x[2]*x[2])));
source = con;
dS[eqn] = 0;
return source;
}

which error appears? did you try to compile instead of interpret it?

no i didn't compile it, but i think this is because of the math.h header , any comment on that ?
btw fluent shuts down rapidly so i cant catch the error

there is no need to include math.h since it is included already by the udf.h
