how to solve "parse error'?

wanghong

HI,everyone, My UDF¡¯name is t.c. but when compiling it in FLUENT[3d,segregated,lam],that is, define user-defined functions interpreted my 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.cError: t.c: line 1: parse error. My program is as follow: /************************************************** ********************/ /* 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) }

that is,the computer can not find head files of UDF.Why?? thanks.
