The cross-section of the domain is similar to a pipe. The objective is to heat metal particles located at a certain distance from the inlet of the pipe using a specified value of heat flux. I don't know the resulting temperature so I cannot specify the temperature of the particle using DPM Source Macro as:

#include "udf.h"
#include "dpm.h"
DEFINE_DPM_SOURCE(dpm_source,c,t,S,strength,p)
{
real xc[ND_ND]; // array of cell coordinates
C_CENTROID(xc,c,t); // retrieves the cell coordinates
if (xc[0] > 3) // only if this cell belongs in the domain where x > 3 m
{
P_T(p) = 500; //temperature of the metal particle increases to 500K
}
}

Any Suggestions?
