hi,everyone, My UDF¡¯name is t.c., but when compiling it in FLUENT[3d,segregated,lam],that is, define--- user-defined------ functions -----interpreted,the computer give me following information: Cpp--IC:\FLUENT.INC\FLUENT\fluent6.0/src - IC:\FLUENT.INC\FLUENT\fluent6.0/cortex/src -IC:\FLUENT.INC\FLUENT\fluent6.0/client/src -IC:\FLUENT.INC\FLUENT\fluent6.0/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" t.c Error: t.c: line 1: parse error.

Who can its reason? HOW TO deal with it?help please!

Why do not publish this code here we can check it and give your the feedback about the problem

my code is as following: /************************************************** ********************/ /* unsteady.c */ /* UDF for specifying a transient velocity profile boundary condition */ /************************************************** ********************/ #include "udf.h" DEFINE_PROFILE(unsteady_velocity, thread, position) { face_t f; begin_f_loop(f, thread) { real t = RP_Get_Real("flow-time"); F_PROFILE(f, thread, position) = 20. + 5.0*sin(10.*t); } end_f_loop(f, thread) }
