Hello everyone,

I'm a french intern in National Technical University of Athens and I'm currently trying to compile a UDF file (2DGaussian.c) in order to create a moving heat source in ANSYS Fluent but the following error message appears :

Setting Post Processing and Surfaces information ... Done.

Done.

Could anyone help me with this problem please?

Can you try compiling with the CLANG (built in) compiler when launching Fluent from the Start menu?
