Abstract: A fluid structure interaction simulation method includes a graph information forming process to form graph information of nodes obtained by discretising a computing region for each of a fluid and a structure that are represented by meshes, and a main time development loop process to simulate a physical phenomenon. The loop process includes arranging IMEs (Interaction Mediating Elements) that move with a displacement of the structure, on a boundary of the structure, defining, within the IME, correcting functions of a pressure and a velocity of the fluid that interact with the pressure and the velocity of the fluid and the displacement of the structure, and executing a simulation based on the correcting functions, in a state in which the meshes of the fluid are mismatched to the meshes of the structure.

Abstract: A method includes: obtaining designated 3D template for a designated part in a heart; generating 3D annulus data representing an annulus of a heart valve identified as a reference of transformation, from a cross-section image in a plane passing through an axis within the annulus of the identified heart valve in 3D volume data generated from tomographic images; identifying a first point on the annulus of the identified heart valve in the designated 3D template and a second point on the annulus represented by the 3D annulus data; arranging n starting points from the first point on the annulus of the identified heart valve in the designated 3D template and n target points from the second point on the annulus represented by the 3D annulus data; and calculating movement destination coordinates of vertices of polygons relating to the designated 3D template to transform the designated 3D template.

Abstract: According to an aspect of the embodiment, a user apparatus transmits a parameter on generation of drawing data to each of drawing data generation apparatuses through a network, to assign generation processing of the drawing data to each of drawing data generation apparatuses. The user apparatus receives the drawing data generated based on the parameter by each of the plurality of drawing data generation apparatuses through the network, and displays the received drawing data. The user apparatus changes the parameter corresponding to the displayed drawing data, and displays a new drawing data corresponding to the changed parameter.

Abstract: A modeling device is disclosed that easily projects characteristic information obtained from an object onto a differently-shaped object, even if the object, from which the characteristic information is obtained, has a complex shape. A modeling device in one embodiment of the present invention includes a virtually electrifying section to calculate an electric potential at a spot in a heart at the time when a predetermined voltage is applied to the heart, and a projecting section to project a fiber orientation onto a heart model created on the basis of shape information that is input to the input section. The projecting section specifies a spot to be a target of projection on the basis of the electric potential obtained by the virtually electrifying section. Use of the electric potential in specifying the spot makes it possible to easily project the fiber orientation onto any heart having complex and various shapes.

Abstract: A vector computer system includes a plurality of memory banks 40, a vector processor 11, and a plurality of additional processing units 30 each of which is connected to one of the memory banks 40. Each of the additional processing units 30 reads data from the corresponding memory bank 40 by referring to an address designated by the processor 11, and performs a designated operation about the data. Then the additional processing unit 30 stores the result of the operation into the designated address.

Abstract: Method is provided for calculating a matrix by using a vector computer with at least one vector processor and a plurality of memory banks. The method controls procedure of the calculation so that the memory banks may be accessed in a constant stride. Furthermore, the method can be applied to vector computers having various queue length and the number of the memory banks. As a result, rapid operation can be made compared to the existing method. In addition, without further outlay, other dependencies than the known 5-point stencil or 7-point stencil can be taken into account.
