Question Relaxation between two load steps

Hello community,


maybe you can help me further. I have two load steps. The first step is a heating step of 0.01 seconds. The second step is a 0.01 second cooling step. Between these two steps, the system should "relax", so no more heat to be entered. How can I specify this in the udf?
My previous code looks like this:
Code:
#include "udf.h"
DEFINE_PROFILE(unsteady_temperature, thread, position)
{
 face_t f;
 real a; 
 real m = 700;
 begin_f_loop(f, thread)
 {
  t = CURRENT_TIME; 
if          	( t > 0.0 && t <= 0.01 )	{ F_PROFILE(f, thread, position) = ( m * t )+293.15 ; }  // linear heating
else if	( t > 1.01 && t <= 1.02 )     { F_PROFILE(f, thread, position) = ( m * t )+1000.15 ; } // linear cooling
else { Do nothing and relax???????? }
 }
 end_f_loop(f, thread)
}
Greetings Kauf
