Hi guys,
I'm not able to find what's wrong with this code:

Code:
#include "udf.h"
#include "materials.h"

#define sootDens 1000;
#define C_1_coef 4;
#define C_2_coef 0.014388;
#define C_3_coef 3.72;

DEFINE_PROPERTY(udf_abs_coeff,c,t)
{

real cellTemp;
real cellRho;
real cellM1;
real sootvf;
real absCoeff;

cellTemp = C_T(c,t);
cellRho = C_R(c,t);
cellM1 = C_UDSI(c,t,0);
sootvf = cellM1*cellRho/sootDens;
absCoeff = C_3_coef*C_1_coef*sootvf*cellTemp/C_2_coef;


return absCoeff;

}
the aim is to define the absoprtion coefficient linked to the UDS mass fraction and temperature.
The problem rises when i try to build the library, the software returns:

..\..\src\udf_absorption_coef.c(22) : error C2100: riferimento indiretto non valido
..\..\src\udf_absorption_coef.c(22) : warning C4552: '/': l'operatore non ha effetto. Previsto operatore con effetto collaterale.

P.S. I need to make the udf suitable for parallel processing

Thank you in advance

Paolo
