Hello,

I have a 2D spiral geometry and I am trying to calculate the temperature gradient along the wall. I have written a UDF code to calculate it but it is not getting compiled. Can anyone help me out here ? I am attaching my udf file here.

#include "udf.h"

DEFINE_ADJUST(tempgrad,d)
{
	Thread *t;
	cell_t c;
	face_t f;

	thread_loop_c(t,domain)
	{
		begin_c_loop(c,t)
		{
			C_UDSI(c,t,0)=NV_Mag(C_T_G(c,t));
		}
		end_c_loop(c,t)
	}
}

DEFINE_ON_DEMAND(store_gradient)
{ 
	
	Domain *domain;
	cell_t c;
	Thread *t;
	domain=Get_Domain(1);
	
	thread_loop_c (t,domain)
	{
		begin_c_loop (c,t)	
		{
		C_UDMI(c,t,0) = NV_MAG(C_UDSI_G(c,t,0));
		}
	end_c_loop (c,t)
	}
}
