$assignsumrange is a special command to ask the program to integrate certain area's n,p,activated dopant, radiative,nonradiative, Auger ,and generation. The result will be output in *.Nsum file. If this command is not used, the program will output the summation of total area. If this command is used, the program will output the summation of assigned areas.
$assignsumrange N_sum x_min x_max y_max y_min x_min x_max y_max y_min ... ... Repeat N_sum types
$assignsumrange 2 2.0 100.0 4.303 4.300 2.0 100.0 4.313 4.310
This example tried to get summation of those parameters in assigned area.
