Default ADJUST udf

Hi I am doing simulation pressure transients due to combustion. But inspite of combustion i am assuming a reaction rate and introducing that much amount of products in to the domain. In order to correct the temparature and pressure of the product species, I am trying to adjust the pressure and temparature by ADJUST Function. Is it possible? If so, would you please correct the UDF given below?

DEFINE_ADJUST(adjust_fcn,domain) { Thread *t; cell_t c; domain = Get_Domain(2);//2 indicates the phase-1 in the mixture. thread_loop_c(t,domain) {

begin_c_loop(c,t)

{

C_P(c,t) = 18298675.0;

C_T(c,t) = 1660.0;

}

end_c_loop(c,t) } }

Thanks a lot in advance...

try like this:

Domain* domain1=Get_Domain(2); thread_loop_c(t,domain1) and so on.

domain is available in your udf, I don't think is aloud to reassign domain to another domain.

I think this is proper.

#include "udf.h"

DEFINE_ADJUST(adjust_fcn,domain) { Thread *t; cell_t c; domain = Get_Domain(2); thread_loop_c(t,domain) {

begin_c_loop(c,t)

{

C_P(c,t) = 18298675.0;

C_T(c,t) = 1660.0;

}

end_c_loop(c,t) } }
