Abstract:
A numerical analysis mesh generating method comprising the steps of:inputting a geometric model under analysis; selecting a verification model having a geometry analogous to said geometric model; corresponding said geometric model to said verification model in terms of the geometry; reading a previously created mapping model approximated from said verification model with a lattice; modifying said mapping model of said verification model from a geometric correspondence between said geometric model and said verification model to create a mapping model for said geometric model; and mapping lattice points of said created mapping model for said geometric model to said geometric model to create a numerical analysis mesh, wherein in said step of corresponding said geometric model to said verification model in terms of the geometry, edges of both said models are corresponded, wherein for portions which cannot be corresponded in said step of corresponding the geometries, newly adding edges and faces to said mapping model of said verification model is performed in said mapping model creating step, wherein in said mapping model creating step, a direction of each edge cannot be corresponded in said step of corresponding the geometries is preliminarily decided in one of six directions constituting a mapping model, determination is made as to whether or not a mapping model can be created with preliminarily decided edges, and when a mapping model cannot be created, each direction of the preliminarily decided edge is changed in attempt to create a mapping model.
