Dear Everybody I face with following error as I interpret any UDF in fluent. Could anyone help me please?

Error: cpp -I"C:\Fluent.Inc\fluent6.3.26/src" -I"C:\Fluent.Inc\fluent6.3.26/cortex/src" -I"C:\Fluent.Inc\fluent6.3.26/client/src" -I"C:\Fluent.Inc\fluent6.3.26/multiport/src" -I. -DUDFCONFIG_H="" "C:\Documents and Settings\home\Desktop\mohsen\Samp e\unsteady_velocity.c"

Thanks a lot.

Store the UDF, case and mesh file in a single directory and better do not store on the desktop. Try this once and get back if you have any problem

Hello there,

I have the same problem and have tried what you suggested but the same error still persists. However, as a very new UDF user, I am wondering if I have to get a C-Compiler installed on my machine first before using UDF? If so, it would be very kind of you if you can please tell me step-by-step how.

Thank you so much for your help, very appreciate it.
