Patent number: 11393593Abstract: In a biological simulation apparatus, an operation unit represents a structure domain where tissues of a biological organ exist by a structure mesh model based on a Lagrange description and a fluid domain where fluid inside the biological organ exists by an ALE fluid mesh model based on an ALE description method. In a fluid-structure interaction simulation, the operation unit deforms the structure mesh model, and then deforms the ALE fluid mesh model so as to form no gap on a first interface between a domain where a site other than a certain site of the biological organ in the structure domain exists and the fluid domain or no overlap with the structure domain. The operation unit captures a position of a second interface between a domain where the certain site exists and the fluid domain by using the ALE fluid mesh model as a reference.Type: GrantFiled: December 30, 2016Date of Patent: July 19, 2022Assignees: FUJITSU LIMITED, THE UNIVERSITY OF TOKYOInventors: Toshiaki Hisada, Seiryo Sugiura, Takumi Washio, Junichi Okada, Ryozo Nagai, Taro Kariya, Masahiro Watanabe, Kohei Hatanaka, Machiko Nakagawa, Yoshimasa Kadooka
