*.Nsum

The Nsum file is doing the integration of different regions n, p, Nd(a) (activated dopant), Radiative, nonradiative, Auger, and, generation The format is

 VG  VD  VS  $\int_{all} n(r) dr^{2}$ $\int_{all} p(r) dr^{2}$ $\int_{all} Nd(r) dr^{2}$ $\int_{all} Rad(r) dr^{2}$ $\int_{all} non_Rad(r) dr^{2}$ $\int_{all} Auger_non(r) dr^{2}$ $\int_{all} generation(r) dr^{2}$  $\int_{r1} n(r) dr^{2}$ $\int_{r1} p(r) dr^{2}$ $\int_{r1} Nd(r) dr^{2}$ $\int_{r1} Rad(r) dr^{2}$ $\int_{r1} non_Rad(r) dr^{2}$ $\int_{r1} Auger_non(r) dr^{2}$ $\int_{r1} generation(r) dr^{2}$ $\int_{r2} n(r) dr^{2}$  $\int_{r2} p(r) dr^{2}$...

r1 means region 1.
r2 means region 2.
it will repeat and upto 20 regions
