How to define Heat flux UDF in ansys in Boundary Condition?
 

Hello,

I have written the Heat Flux UDF and i want to define it in Boundary Condition, i mean in the wall. How can i do ?


# include "udf.h"
# include "unsteady.h"

DEFINE_EXECUTE_AT_END (execute_loop)
{
face_t f;
Thread *t;
real c_time=0.0000;
real q;
c_time=CURRENT_TIME;

if (c_time>0.00 && c_time<2700)
{
q=500;
}

if ((c_time>=2700)&&(c_time<=5400))
{
q=-500;
}
}

Ansys FLuent Customization manual

look for DEFINE_PROFILE macro

best regards
