The present invention has been made to provide a technique capable of contributing to a reduction in operational burden on workers and an increase in operating accuracy in a generation process of a mesh for numerical analysis for a geometric model. A numerical analysis mesh generation apparatus generates a mesh for use in performing numerical analysis for a geometric model to be analyzed. The apparatus comprises: a reference surface selection section that selects one surface from a plurality of surfaces constituting the geometric model as a reference surface; an edge projection section that projects, in a predetermined direction, edges of the geometric model located in a predetermined direction away from the reference surface selected by the reference surface selection section on the reference surface; an interval determination section that determines an interval between edges projected on the reference surface by the edge projection section; a grouping section that groups two or more edges with one of the two or more edges set as a representative edge when the interval determination section determines that the interval between them is smaller than a predetermined interval; and a mesh generation section that generates a mesh for the reference surface based on a surface divided using the edges grouped by the grouping section.
