DEVICE AND METHOD FOR GENERATING TWO-DIMENSIONAL FINITE ELEMENT MESH USING TRIANGULAR SIX NODE HIGHER ORDER ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a generating device for two-dimensional finite element mesh which performs the numbering of the whole main nodes and the numbering of the whole higher order nodes without using universal support software and uses triangular six node higher order elements and to provide its method. ;SOLUTION: This device is provided with an auxiliary point number generating part 1 which numbers an auxiliary point number for dividing each small area into a mesh shape based on the number of element divisions in x and y axial directions, the number of small area divisions, the auxiliary point numbers of four corners of a small area and their coordinates values, a node number generating part 2 which numbers a new continuous number to the main node and higher order node of each element based on the whole auxiliary point numbers and their coordinates values, a higher order element generating part 3 which extracts a node number constituting each element based on the node number and its coordinates values, a higher order node correcting part 4 which calculates the coordinates values of a higher order node from the main node coordinates values of each element based on the node number of each element and its coordinates values, corrects the coordinates values of the higher order node and outputs the whole node numbers after correction and their coordinates values and a data outputting part 5 which outputs node data constituting each element and the coordinates data of the node in every element based on the whole node numbers, their coordinates values and node numbers constituting each element.;COPYRIGHT: (C)2000,JPO
