Title:
INSPECTION METHOD FOR FINITE ELEMENT MODEL
Document Type and Number:
Japanese Patent JP2761134
Kind Code:
B2
Abstract:
PURPOSE: To provide an inspection method for finite element model for strictly inspecting whether definition data of finite element is in a right node sequence or not.
CONSTITUTION: This method is provided with a table preparation means 11 preparing a node table storing the coordinate value of a node from data and an element table storing the constitution node of the element based on the data of a three-dimensional geometry model which is preliminarily divided into a finite element, an element data take-out part 12 taking out at least two surfaces from the three-dimensional geometry model shape based on the data within the element table, a calculation means 13 calculating a normal vector of a prescribed surface from each surface which was taken out and a judgment means 14 judging the presence or absence of the existence of each node constituting a surface which is different from a surface in the direction of the calculated normal vector. Based on the judgment result of the judgment means 14, whether a finite element model is good or bad is inspected.
