Patent ID: 7439971

Claim:
A mesh generating method for numerical simulation, generating mesh data for numerical simulation of one (1) piece of an analysis target, where there are plural numbers of high-density configuration data, each presenting a configuration surface thereof said one (1) piece of analysis target, comprising the following steps: a step for reading one (1) piece of the configuration mesh data “A” from said plural numbers of the configuration mesh data; a step for generating low-density configuration mesh data “B” through treating a density lowering process for reducing a number of meshes on said configuration mesh data “A”; a step for reading configuration mesh data “C” neighboring to said configuration mesh data “A” from said plural numbers of configuration mesh data; a step for generating mixed and combined configuration mesh data “D” mixing a low density portion and a high density portion therein, through combining said low-density configuration mesh data “B” with said configuration mesh data “C”; and a step for generating combined low-density configuration mesh data “E” through treating said density lowering process for reducing a number of meshes on the high density portion of said mixed and combined configuration mesh data “D”, wherein final combined low-density configuration mesh data is generated through repeating every said processes up to said process for generating the combined low-density configuration mesh data “E”, until when none of said plural numbers of configuration mesh data remains, and mesh data for numerical simulation is generated from said final combined low-density configuration mesh data.
