Abstract:
A computer simulation method for obtaining a physical quantity at a position in an electrical element, comprising the steps of:(a) expressing a first function representing a first physical quantity satisfying a Poisson's equation with respect to a first variable indicating a given position in an analysis space of said electrical element, said analysis space comprising at least one region having a boundary comprising information on position and boundary condition in a form of a first integral with a difference as a first integrand between a product of a second function representing said first physical quantity with respect to a second variable indicating a position on said boundary and a first derivative representing a normal component on said boundary out of a differentiated result of a first Green's function on said first and second variables and said first physical quantity with respect to said second variable and a product of said first Green's function and a second derivative representing a normal component on said boundary out of a differentiated result of said second function with respect to said second variable, said boundary as a first integral region, and said second variable as a first variable of integration; and (b) substituting said first integral sequentially into either one of said second function and said second derivative that is not given as said boundary condition while updating said first variable of integration so as to provide a computer simulation to obtain said physical quantity at said given position in said analysis space of said electrical element by using said boundary condition based on a distribution of said first physical quantity.
