MESH GENERATION DEVICE AND ITS METHOD FOR GENERATING MESHES HAVING A BOUNDARY PROTECTIVE LAYER

A mesh generation device comprising a boundary protective layer generating unit, a mesh point positioning unit, a triangular mesh generation unit and a triangular mesh checking unit, characterized in that the triangular mesh generating unit generates triangular meshes restrictively in the region where the boundary protective layer may be destroyed by some triangular meshes as the first stage, and generates triangular meshes in the remaining region as the second stage, and that the triangular mesh checking unit checks whether or not the generated triangular meshes are destroying the boundary protective layer after the completion of the processing in the first stage by the triangular mesh generating unit.
