I'm a new user of fluent in the version included in ANSYS13. I've read a lot of posts related with the problem that I'm having while trying to run am already compiled UDF I built that requires the estimation of the gradient of a UDS that is running OK in a transient simulation.

I've tried solve/set/expert temporary solver memory [yes], giving a determined value to the UDS during a DEFINE_INIT, etc.

I read somewhere that by initializating the calculation without having hooked the ADJUST and doing the hook after a couple of iterations might solve the problem, but I have not managed to do so...

The UDF I built is:

#include "udf.h"

DEFINE_ADJUST(E_field,d)
{
Thread *t;
cell_t c;
real conduct,tempe,d1;

d1=3.213e-034;

if (! Data_Valid_P())
return;*/

if(NULL!=THREAD_STORAGE(t,SV_UDS_I(0))&&NULL!=T_ST ORAGE_R_NV(t,SV_UDSI_G(0)))
{
thread_loop_c(t,d)
{
if (FLUID_THREAD_P(t))

{
begin_c_loop(c,t)
{
tempe=C_T(c,t);
conduct=d1*pow(tempe,9.);
C_UDMI(c,t,0)=conduct;
C_UDMI(c,t,1)=-conduct*C_UDSI_G(c,t,0)[0];
}
end_c_loop(c,t)
}
}
}
}

Thanks in advance for any clue you can give me about it.
