Hey, hello stage81! I got it.
for your problem, I think UDF is:
/**************************************/
#include "udf.h"

DEFINE_SOURCE(energy_source,c,t,dS,eqn)
{
real x[ND_ND];
real source;

C_CENTROID(x,c,t);

if (x[1]==10.)

source = 10000.;
else
source = 0.;

return source;
}
/******************************************/
Best wish for you!
