PROBLEM TO BE SOLVED: To improve the accuracy of analysis results to be obtained without significantly changing a program for a zooming analysis using a finite element method. SOLUTION: The analyzer executes a global analysis of a structure (step 401) and calculates strain at each nodal point from the strain of each element of a global model (step 402). Next, a secondary coefficient of a quadratic function showing the displacement in each nodal point of a micro model is calculated from the strain of each nodal point (step 403). A constant term and a primary coefficient are calculated from the displacement of each nodal point of the global model (step 404). The displacement at each boundary nodal point of the micro model is calculated by using the quadratic function (step 405). Then, a micro analysis is executed (step 406). COPYRIGHT: (C)2007,JPO&INPIT
