Hi I am attempted to use UDF to define dimensionless temperature in order to use it in post processing results I wrote it as below :

#include "udf.h"

DEFINE_ON_DEMAND(on_demand_calc)
{
Domain *d; /* declare domain pointer since it is not passed as an
argument to the DEFINE macro */
real th = 298.3899;
real tc = 297.6101;
real temp;
Thread *t;
cell_t c;
d = Get_Domain(1); /* Get the domain using Fluent utility */

/* Compute temperature function and store in user-defined memory*/
/*(location index 0) */

begin_c_loop(c,t)
{
temp = C_T(c,t);
C_UDMI(c,t,0) = (temp-tc)/(th-tc);
}
end_c_loop(c,t)

}


I interpreted it successfully but when I select execute for demand it give me the following error:

Warning: E:\\Project current year\\paper work\\output.C: line 9:
Error: received a fatal signal (Segmentation fault).

So is there problem with the UDF? any reply please?
