METHOD AND DEVICE FOR GENERATING NUMERIC DATA FOR CALCULATION FROM ANALYTIC MODEL BY FINITE ELEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To decrease the calculation quantity and memory capacity needed for a structure analysis by a finite element method, etc., even when the shape of a structure is complicated and elements and nodes are large in number. SOLUTION: An analytic model for the structure is roughly divided into rough divisional elements first and rough divisional elements which are arranged in one direction is set as one array to set the analytic model for the structure as multiple arrays 1 and 2; and the rough divisional elements are further divided into fine divisional elements FE1 to FE20, node numbers 1 to 15 and 1 to 21 are set to each of nodes of the fine divisional elements according to the arrays, and multiple arrays are integrated to obtain the whole analytic model. Then the node numbers at each of the nodes of the fine divisional elements are charged into node numbers of the whole analytic model.
