ELEMENT DIVISION APPARATUS, METHOD THEREOF, PROGRAM THEREOF, AND RECORDING MEDIUM CONTAINING THE PROGRAM

摘要

Original data containing 3-dimensional shape node point information and element 3-dimensional information constituting a mesh created by 3-dimensional CAD creation software or the like is set/input into a 3-dimensional original element division apparatus (1) and the data is recognized by 3-dimensional shape data recognition means (11). According to coordinate information on the recognized original data node point information, the middle point between adjacent nodes, a center of surface constituting an element, and center of gravity of the element are calculated by using the average of coordinate values, thereby setting a new node. The element is divided into hexahedron elements by a surface composed of a line connecting the middle point node and the center node and a line connecting the center node and the center-of-gravity node.
