Hi guys
i am trying to simulate a constant volumetric energy source in a specific zone in my domain in fluent so all the cells within that zone would have same source energy . i wrote the below udf but the problem is temperature wouldn't increase within the zone ....i have already applied the udf to the specific zone....any idea? thanks

#include "udf.h"

DEFINE_SOURCE(energy_source,c,t,dS,eqn)
{
real x[ND_ND];
real source;
C_CENTROID(x,c,t);
source = 50000000000 ;
return source;
}
