The following code uses a UDS and an EXECUTE_AT_END Macros. It gets interpreted and hooked, but whenever I run the simulation, I seem to get a segmentation error. Could somebody please help me out in pointing what the error is? New to UDFs.

Code:
include "udf.h"

enum
{
	UDS2
};


DEFINE_EXECUTE_AT_END(execute_at_end)
{
	Thread *t;
	cell_t c;
	float T=C_T(c,t);
		begin_c_loop(c,t)
		{
			C_UDSI(c,t,UDS2)=8.439*pow(10,-4) - (3.81e-6)*T + (6.736e-9)*pow(T,-9) - (3.934e-12)*pow(T,-12);
		}
		end_c_loop(c,t)
}

        end_c_loop(c,t)
}
Have you allocate UDS in the menu?

Edit: I wrote the code without a UDS, but it still seems to give a segmentation fault. Could you please help me point out where my error is? Thanks!

#include "udf.h"
#include "sg.h"



DEFINE_EXECUTE_AT_END(execute_at_end)
{
Domain *d;
Thread *t;
cell_t c;
real T;
d=Get_Domain(8);
thread_loop_c(t,d)
{

begin_c_loop(c,t)
{
T=C_T(c,t);
}
end_c_loop(c,t)
}

}

pakk will become famous soon enough
Maybe your Get_Domain(8) does not exist. Do you really have a multiphase flow with 8 phases???


And for your first code of 31 January: I think you are confusing UDS with UDM.
