FINITE ELEMENT ANALYSIS METHOD, FINITE ELEMENT ANALYSIS DEVICE, ANALYSIS SERVICE SYSTEM, AND RECORD MEDIUM STORING FINITE ELEMENT ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a finite element analysis method, a finite element analysis device, and an analysis service system, which are easy to use both beginners and experienced even if a material of an analysis object is a composite material, and to provide a record medium storing finite element analysis program.;SOLUTION: A composite of finite elements includes: parent finite elements in which finite element divides an analysis area into a mesh; and a single element or plural child finite elements each of which has arbitrary plural nodes of parent finite elements as angular nodes. A computer has a function to calculate the ratio of physical property values and/or a prediction error between the child elements and the parent elements in a data input step, and if unacceptable errors are predictable, a warning is output, and the analysis is suspended as desired. Based on the input data, the computer calculates physical values of the parent element and child elements composing the complex element and dimension of the child elements using a pattern specification method based on local element number of compound element, and/or an element specification method to search based on connectivity.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
