摘要： There is enabled an accurate fluid-structure interaction simulation on a biological organ having a deformable site that has an interface difficult to track. An operation unit (12) represents a structure domain in which tissues of a biological organ exist by using a structure mesh model (2) based on a Lagrange description method and a fluid domain in which fluid inside the biological organ exists by using an ALE fluid mesh model (3) based on an ALE description method. In addition, when performing a fluid-structure interaction simulation, the operation unit (12) deforms the structure mesh model (2) along with the progress of the simulation. Specifically, the operation unit (12) deforms the ALE fluid mesh model (3) in such a manner that no gap is formed on a first interface (4) located between a domain in which a site other than a certain site (2a) of the biological organ in the structure domain exists and the fluid domain or no overlap is formed with the structure domain, to track the first interface (4). The operation unit (12) captures a position of a second interface (5) located between a domain in which the certain site (2a) in the structure domain exists and the fluid domain by using the ALE fluid mesh model (3) as a reference.

摘要： There is enabled an accurate fluid-structure interaction simulation on a biological organ having a deformable site that has an interface difficult to track.
An operation unit (12) represents a structure domain in which tissues of a biological organ exist by using a structure mesh model (2) based on a Lagrange description method and a fluid domain in which fluid inside the biological organ exists by using an ALE fluid mesh model (3) based on an ALE description method. In addition, when performing a fluid-structure interaction simulation, the operation unit (12) deforms the structure mesh model (2) along with the progress of the simulation. Specifically, the operation unit (12) deforms the ALE fluid mesh model (3) in such a manner that no gap is formed on a first interface (4) located between a domain in which a site other than a certain site (2a) of the biological organ in the structure domain exists and the fluid domain or no overlap is formed with the structure domain, to track the first interface (4). The operation unit (12) captures a position of a second interface (5) located between a domain in which the certain site (2a) in the structure domain exists and the fluid domain by using the ALE fluid mesh model (3) as a reference.

摘要： Processing load for displaying a numerical simulation result on a drawing apparatus is reduced. The drawing apparatus is provided for drawing a flow line representing flow of a fluid in a 3D-space as a 2D image viewed from an arbitrary viewpoint position. The drawing apparatus includes a flow line generation section configured to generate the flow line from a predetermined start position; a view setting section configured to set the viewpoint position in the 3D-space; a band-of-facets forming section configured to form a band of facets connecting a plurality of polygon facets along the flow line based on the set viewpoint position; and a texture mapping section configured to map texture onto each of the plurality of polygon facets. The texture represents reflected light on the band of facets with respect to a light source placed at a predetermined position in the 3D-space.
