Hi, Every one

My aim is to use UDF in defining a unsteady inlet B.C. but the first try with example given in manual failed. The problem is as follows, CPP -ID:\FLUENT.INC\fluent5.4/src -ID:\FLUENT.INC\fluent5.4/cortex/src -ID:\FLUENT.INC\fluent5.4/client/src -ID:\FLUENT.INC\fluent5.4/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" profile_v.c Error: profile_v.c: line 1: parse error. The UDF routine is directly from "Parabolic inlet profile in turbine vane " in user manual. Can you tell me what was the reason and how to correct it.

Next I want to modify periodic B.C to Time-Delay Periodic B.C., Is it able to be realized? How to do?

Thanks

Hi,I have met this problem.Later I find that I compiling the provile_v.c.txt instead of provile_v.c because of the hidden txt.

Fang,

Thank you for your reply.

I have solved the first problem. Just put *.c file into *.cas Directory. The most difficult problem is how to change periodic B.C to Time-Delay or Phase-Delay Periodic B.C.? Can you give me help?
