udf compile error
 

Hi; I use this Udf to define unsteady velocity inlet profile.

unsteady.c #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) }

but when I compile it, Fluent report this error: cpp -ID:\FLUENT.INC\fluent6.0/src -ID:\FLUENT.INC\fluent6.0/cortex/src -ID:\FLUENT.INC\fluent6.0/client/src -ID:\FLUENT.INC\fluent6.0/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" unstveloc.cError: unstveloc.c: line 1: parse error. what should i do?please help me. thanks.

Firstly, don't use cpp, use g++ or c++. I check it out, where is the problem, and let you know if there is any.

The mistake is in defining variables. Firstly define variable, then start program. You have to define real t before starting f_loop.

Hi vinod; I check it,but the error appears again.

Compile it after making the changes I told you. Define t out of the loop

Else send me your ID. I'll send you a file. Make sure you have udf.h file in the same directory where you .c file is.

After making the changes you told,I compiled it. But it didn't solve the problem. rawin.
