Hello everyone, I combined udf and scheme to make FLUENT automatically stop calculating when the wall temperature and pressure reach conditions. But it is not possible to realize it.here is my code with many references. thank you

#include "udf.h"
#include "math.h"
#include "var.h"

DEFINE_ADJUST(interrupt_1, d)
{

	cell_t cell;
	Thread* thread;
	Domain* domain;
	real temp, pressure, NV_VEC(dist);
	int ID = 12;  
	face_t f;
	Thread* t;
	cell_t c0, c1;

	domain = Get_Domain(1); 


	thread = Lookup_Thread(domain, ID);



	  begin_f_loop(f, thread)
	     {
		      c0 = F_C0(f, thread);
		      c1 = F_C1(f, thread);


		      if (THREAD_ID(thread) == ID)
		      {
			       t = THREAD_T0(thread);
			       if (c0 != -1)
			       {

				         temp = C_T(c0, t);
				         pressure = C_P(c0, t);

				         if (temp > 250.0 && pressure > 140)
				         {

							 RP_Set_Integer("interrupt/flag",5);  
							 Message("Temperature exceeds 2500K and Pressure exceeds 1.4MPa. Stopping simulation...\n");
				         }
			       }
		      }
	     }
	  end_f_loop(f, thread)			
}

schemem code

(rp-var-define 'interrupt/flag 0 'integer #f)
(define (interrupt-end-of-timestep)
  (if (> (%rpgetvar 'interrupt/flag) 0)
      (begin (cx-interrupt-end-of-timestep))))
