Hello,

I've tried to interpret a simple "DEFINE_SOURCE" udf in Fluent, but I always get the message "line 2: syntax error". I've checked my source code (below) and found no problem with it. Can anyone advice me on this? Thank you.

#include "udf.h"

DEFINE_SOURCE(mass_sink,c,t,dS,1) {

real sink;

sink=-0.4;

dS[1]=0;

return sink; }

try this:

#include "udf.h"

DEFINE_SOURCE(mass_sink,c,t,dS,eqn) {

real sink;

sink=-0.4;

dS[eqn]=0;

return sink; }
