An analytical mesh generation device (100) includes a shape model input unit (102) for inputting a shape model of an analytical subject, a mesh size input unit (103) for inputting a size of a hexahedral mesh to be generated, a mesh generation region extraction unit (104) for extracting a mesh generation region for generating the hexahedral mesh from the shape model using the mesh size (D4), and a hexahedral mesh generation unit (105) for generating the hexahedral mesh for the extracted mesh generation region.
