Abstract
A two-dimensional mesh is generated on a plane perpendicular to the rotation axis. At this time, a ring-shaped gap is provided between the rotor and the stator, and portions facing the ring-shaped gap are equally divided into the same number of parts. An initial three-dimensional mesh is generated by joining together a plurality of two-dimensional meshes in the direction of the rotation axis while rotating the two-dimensional meshes. A boundary surface is formed in a cylindrical gap composed of a stack of the ring-shaped gaps, and a three-dimensional mesh is generated by filling the cylindrical gap with a plurality of polyhedrons, including polyhedrons comprising each of surface elements constituting the stator-side mesh surface, rotor-side mesh surface and boundary surface as one face.
