problems on multi-file udf compiling
 

Hello Guys, I meet a problem on the multi-**.c-udf-file compling in fluent.

since the function is complex, I put some functions in a seperated files, and add both of them into the "source file". However, the compling is failed.

the example files are as follows.

***************************
major.c:

#include "udf.c"

DEFINE_CG_MOTION (****)
{
real FUNC();
xxxxxx;
FUNC();
xxxxx;
vel[0] = xxx;
return;
}

*************************
FUNC.c:

real FUNC()
{
real A;
xxxx;
return A;
}
************************

How can I deal with the problem?

Thx a lot!

Btw:
 

When code is lile,

**********************
major.c:

#include "udf.c"

DEFINE_CG_MOTION(***)
{
real FUNC();
vel[0]=xxx;
return;
}

real FUNC()
{
real A;
...
return A;
}
**************************

that's OK.
