Hi,

I'm starting to play with DEFINE_WSGGM_ABS_COEFF so I can customize the absorption coefficient calculation.

I'm testing with the simplest code, just to see if it works:

#include "udf.h"
#include "materials.h"
DEFINE_WSGGM_ABS_COEFF(user_wsggm_abs_coeff, c, t, xi, p_t, s, soot_conc, Tcell, nb, ab_wsggm, ab_soot)
{
Material *m = THREAD_MATERIAL(t);
*ab_wsggm = 0.3;
}

THE PROBLEM IS
- It works fine in parallel on my laptop Fluent 14.5.7 - Windows 8.1, I get an absorption coefficient of 0.3 everywhere.
- It crashes in parallel on a Fluent 14.5.7 - Linux CentOS 5.10 cluster. There is no error message when the udf is interpreted, but when the iterations start I get this message repeated over and over until the print buffer is exceeded : Chip_Exec_C: parameter 4: invalid type (1031989648)
the number in parentheses is not always the same

What am I missing? I don't think it's necessary to parallelize a udf for a property definition.
Thanks
François
