ABSTRACT:
Based on rectangular element data constituting a boundary surface that separates a rotating machine into a stator-side portion and a rotor-side portion, and polygonal or polyhedral element data constituting the stator-side portion and the rotor-side portion excluding the boundary surface, tetrahedral elements including nodes of each of the stator-side portion and the rotor-side portion are created, a node is created at an arbitrary distance from the gravity of the rectangular element in a normal direction for each of the rectangular elements on the boundary surface, mesh division is performed for the tetrahedral elements based on the node at the arbitrary distance and nodes on the boundary surface, and mesh division is further performed based on nodes of the stator and the rotor.
