Hi, I have amount of heat flux let's say its 2000 W/m2. I want to add it in the face of the cell which I already have it in UDMI.

Please help

DEFINE_HEAT_FLUX(heat_flux, f, t, c0, t0, cid, cir)
{
begin_f_loop(f,t){
if(F_UDMI(f,t,1)==1){ //apply heat
cid[0] = 2000;
}
}
}

you need to define cid[1] and cid[2], otherwise it will not work

I dont understand what does it mean by cid[1] or cid[2]?
I am not sure what does it mean with different number.
does cid[0]=2000 mean 2000 w/m2 in the face?

You need to take into account how the heat transfer coefficient is calculated by Fluent.

is it a good idea?

/* Wall Heat Generation Rate Profile UDF */

#include "udf.h"

DEFINE_PROFILE(wallheatgenerate,thread,i)
{
real source = 0.001;
face_t f;

begin_f_loop(f,thread)
F_PROFILE(f,thread,i) = source;
end_f_loop(f,thread)
}
