My udf is as following, it is just used to test the usage of C_P(c,t).

#include "udf.h"
#define RHOV 0.554

DEFINE_PROPERTY(density,c,t)
{
real rho;
real p = C_P(c,t);
rho = RHOV;
return rho;
}

but an error will appear as following.

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


as we can see in UDF, the density has nothing to do with the pressure. i doubt that it must be an error when C_P(c,t) is used. do you know what's wrong with it? thank you
