Abstract:
1. A numerical analysis mesh generation apparatus comprising: a memory that stores a geometric model; a reference surface selection section that selects one surface from a plurality of surfaces constituting the geometric model stored in the memory as a reference surface for mesh generation automatically; an edge projection section that projects, in a predetermined direction, edges of the geometric model on the reference surface so as to generate edge lines on the reference surface automatically, the edges located away from the reference surface; an interval determination section that determines an interval between the edge lines on the reference surface automatically; a grouping section that groups two or more edge lines with one of the two or more edge lines set as a representative edge line automatically when the interval determination section determines that the interval between the edge lines is smaller than a predetermined minimum mesh size; a mesh generation section that generates a mesh having a specified size on the reference surface based on the edge lines grouped by the grouping section automatically; an extrusion section that extrudes a part of the representative edge line along the predetermined direction based on distance information indicating a distance between the reference surface and a target edge of the edges which projected on the reference surface automatically; and a node shifting section that shift the representative edge line along the reference surface automatically in order to shift the extruded part of the representative edge line to the target edge.
