Default UDF temperature variation

Posts: n/a
Hi. I am new to using UDFs and have read through the help file. I am attempting to create an inlet velocity whose temperature varies sinusoidally every 24 hours. My udf file is given below:

#include "udf.h"


{ real x[ND_ND]; /* this will hold the position vector */

real y;

face_t f;





F_PROFILE(f, thread, position) = 10.*sin(t*(pi/720.)) */ here stands the profile function as a function of time /*




I am receiving an error message when interpreting in fluent:

"cpp -IT:\XP\Fluent.Inc\fluent6.2.16/src -IT:\XP\Fluent.Inc\fluent6.2.16/cortex/src -IT:\XP\Fluent.Inc\fluent6.2.16/client/src -IT:\XP\Fluent.Inc\fluent6.2.16/multiport/src -I. -DUDFCONFIG_H="<udfconfig.h>" U:\4th yr\FYP\2nd\Unsteady\udftempprofile.c Error: U:\4th yr\FYP\2nd\Unsteady\udftempprofile.c: line 1: parse error."

Any help is much appreciated

looks like a syntax error. check if the file-format of you c-file is unix (not DOS) or try to compile the udf instead of interpreting it.
