Grid: A finer grid should exist in those areas of the simulation structure where ion implantation will occur,where p-n junction will be formed, or where optical illumination will change photoactive component concentration. The number of arithmetic operations necessary to achieve a solution for processes simulated, using the finite element analysis method could be estimated as (Np) , where is of order 1.5 - 2.0 and Np is number of nodes.
