Can you show us your UDF? Maybe instead of looping on faces you should loop on cells.Luca

Oh, actually My UDF is really simple. It just is forced moving. So UDF is very simple.

#include "udf.h" DEFINE_CG_MOTION(stem, dt, vel, omega, time, dtime) { vel[1]=0.014; }

Above is all, My UDF. Futhermore, when I tested it using mesh motion at first, there was not any error.

Profile files are much easier for defining motion, once they are set up you don't have to reload them every time you restart Fluent.

As for your error, I'd suggest you contact Fluent support.
