An analysis method of analyzing a discharge phenomenon in an information
processing apparatus having a memory includes calculating differences in
potential between nodes on a first surface of a meshed simulation model
and the corresponding nodes on a second surface thereof based on a
predetermined amount of charge of each node before the discharge and the
permittivity of each element of the simulation model; storing information
concerning a pair of nodes having the difference in potential which
exceeds a Paschen voltage determined from the distance between the nodes;
and analyzing an amount of charge moved due to the discharge and electric
potential distribution after the discharge based on the stored
information and the amount of charge of each node before the discharge
and storing the analyzed amount of charge and the electric potential
distribution.
