help in eulerian-eulerian

Hi everyone, I am trying to simulate a packed bed reactor using eulerian-eulerian approach, but when I run this udf, fluent doesn't function, if anyone knows whats the problem, please help me. Fluent says:

Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

This is the udf

DEFINE_HET_RXN_RATE(hetreaction,c,t,r,mw,yi,rr,rr_ t)
{
*rr=C_T(c,t);
}

May be some property within your udf is not been calculated
Or some NAN number is being calculated in your udf
Then only that problems comes.

Use
printf("%f",variable names)
in ur udf and try to debug which variable is not been calculated properly in ur udf.

Hope taht will help you.

Thanks
SHK
