*.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  $\underset{all}{\int }n(r)d{r}^2$ $\underset{all}{\int }p(r)d{r}^2$ $\underset{all}{\int }Nd(r)d{r}^2$ $\underset{all}{\int }Rad(r)d{r}^2$ $\underset{all}{\int }no{n}_{R}ad(r)d{r}^2$ $\underset{all}{\int }Auge{r}_{n}on(r)d{r}^2$ $\underset{all}{\int }generation(r)d{r}^2$  $\underset{r1}{\int }n(r)d{r}^2$ $\underset{r1}{\int }p(r)d{r}^2$ $\underset{r1}{\int }Nd(r)d{r}^2$ $\underset{r1}{\int }Rad(r)d{r}^2$ $\underset{r1}{\int }no{n}_{R}ad(r)d{r}^2$ $\underset{r1}{\int }Auge{r}_{n}on(r)d{r}^2$ $\underset{r1}{\int }generation(r)d{r}^2$ $\underset{r2}{\int }n(r)d{r}^2$  $\underset{r2}{\int }p(r)d{r}^2$...

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