  • Numerical analysis mesh generating method and apparatus
    Patent number: 6727898
    Abstract: A numerical analysis mesh generating method, wherein a geometric model under analysis is inputted, a verification model having the geometry analogous to the geometric model is selected, the geometric model is corresponded to the verification model in terms of the geometry, a previously created mapping model approximated from the verification model with a lattice is read, the mapping model of the verification model is modified from a geometric correspondence between the geometric model and the verification model to create a mapping model for the geometric model, and lattice points in the created mapping model for the geometric model are mapped to the geometric model to create a numerical analysis mesh.
    Type: Grant
