INITIAL CONDITION SETTING DEVICE AND INITIAL CONDITION SETTING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To obtain an initial condition necessary for collision analysis and spring back analysis as a result of obtaining a simple press molding effect as CAD data.;SOLUTION: An initial condition setting device 10 for CAE analysis with CAD data for isogeometric analysis comprises: a reading part 110 reading CAD data; a decomposition part 120 obtaining face data by decomposing CAD data by a face unit; an expansion calculation part 130 expanding the face data to a shape of a plane by conducting expansion calculation; a temporary sewing part 140 causing coordinates of apexes of the face data to match or close each other without deformation by conducting parallel displacement or rotational transfer of the face data expanded in a shape of a plane in a rigid body manner; and a main sewing part 150 obtaining an expansion shape with a plane shape of the CAD data by matching the coordinates of the apexes of the face data and matching coordinates of nodes on an edge that the face data shares or causing a node on one edge to be shared by another edge.;SELECTED DRAWING: Figure 29;COPYRIGHT: (C)2020,JPO&INPIT
