I wrote a short and simple UDF for Fluent Windows XP, which works in both serial and parallel processing.

However when I take this simulation into Linux, I keep getting the following error:

Error: /home/fluentuser/UDF.c: line 2: Syntax Error

I run fluent from the /home/fluentuser directory and that is where my cas/data is stored.

By the way, the system has recently had a fresh install so all it has on is Redhat and Fluent 6.2.16

Can anyone help me solve the problem,

Thank you

Andrew

P.S. The code is intepreted and reads as follows:

#include "udf.h"

DEFINE_SDOF_PROPERTIES(store, prop, dt, time, dtime) {

/* Define the mass matrix */

prop[SDOF_MASS] = 5000.;

prop[SDOF_IZZ] = 5000.;

hi

is the program written in windows initially and then the same file u r using in linux then u will get error. pls retype ur udf in linux and then try. hope it works i had the same problem.

thanks

Thank you for the suggestion. I changed the format from Dos to UNIX already, and also tried typing it out again in Linux and the same messages.

In my system ( although it is WinXP + Fluent 6.2), the bracket must be specified in a new line like following.

DEFINE_SDOF_PROPERTIES(store, prop, dt, time, dtime) {

Please try.

Thank you everybody. The environments where incorrectly setup when Fluent was installed, so for some strange reason it wouldn't find the UDF even though I started Fluent from the location where the UDF was located.

Thanks again,

Andrew
