Hi everybody

I want to change the temperature of slab inside a furnace in particular time step of a transient simulation, with a DEFINE_ON_DEMAND udf.
After the simulation is completed, I execute the UDF and finnally, procede the calculation for another period of time.
That is something wrong with this approach?

Thank you
Tiago

The UDF was compiled and hooked with success, but althought it is executed without a problem, the temperature of slab ( cell zone solid ) doesn´t change.
Maybe there is something wrong with the UDF, but I can't figure out what could it be.

this is my UDF

#include "udf.h"
#include "mem.h"

DEFINE_ON_DEMAND(Slab_1)
{

Domain *d=Get_Domain(1);
int zone_ID=121, Temp=400, cont;
cell_t c;
Thread *t=Lookup_Thread(d,zone_ID);

begin_c_loop(c,t)
{
C_T(c,t)=Temp;

}
end_c_loop(c,t)


}
