Hi guys, I am a new in Fluent and I am creating a source, whose position changes respect to time. I am using coordinates that are written in a separated text file, so I need to read those coordinates and assign them to an specific array. While interpreting the only the only error that comes out is:

fp = fopen("values.txt","r"); ) /*parse error*/
DEFINE_SOURCE(energ_source,c,t,dS,eqn) /*parse error*/

How is that possible?
How can I overcome that problem? Where could the problem lie?

Well, you have extra parenthesis at the end of the fopen line. Maybe try fixing that first. And I'm not sure if the UDF interpreter allows calls to system libraries, like fopen. You may have to do that as a compiled UDF. But, my Fluent skills are several years out of date at this point, so things may have changed.
