Default Heat Flux calculation inside domain

Hi,

I looked for an option to calculate heat flux in a surface/line (2D) inside domain but only found the option to output heat flux / Total surface heat flux in the boundary walls. Has anyone tried this before? I am also trying to write a udf for this but I am stuck on how to calculate the surface area normal to the heat flux.

I am using this for heat flux calculation. Not sure if this is right yet -

Code:
				C_CENTROID(xc,cell,cell_thread);
				tg_x = C_T_RG(cell,cell_thread)[0];
				tg_y = C_T_RG(cell,cell_thread)[1];
				con = C_K_EFF(cell,cell_thread,0.85);
				tg_n = (pow(pow(tg_x,2)+pow(tg_y,2)),0.5);
				heat_flux = con*tg_n;
Help anyone?
