Abstract:
1. A three-dimensional mesh generation method for generating three-dimensional meshes of a rotating machine composed of a stator and a rotor to derive an output for analysis and display upon a computer system, comprising steps of: setting a boundary surface in a spatial area between the stator and the rotor to separate the rotating machine and the spatial area into a stator-side portion and a rotor-side portion and prescribing shapes of the stator-side portion and the rotor-side portion; dividing the boundary surface into quadrilateral elements; dividing each of the stator-side portion and the rotor-side portion into tetrahedral elements including nodes; creating a point at an arbitrary distance from a center of a gravity of the quadrilateral element to the rotor side in a normal direction for each of the quadrilateral elements constituting the boundary surface and performing mesh division for the tetrahedral elements based on the point at the arbitrary distance and nodes on the boundary surface; and performing mesh division based on nodes of the stator and the rotor to generate three-dimensional meshes of the stator-side portion and the rotor-side portion.
