NUMERICAL ANALYSIS METHOD BY BOUNDARY ELEMENT METHOD AND METHOD FOR PREPARING ANALYSIS MODEL

摘要

PURPOSE:To provide the approximate method for variable distribution reducing the number of variables required for calculating the physical state amount in analysis object body by the numerical analysis using the boundary element method. CONSTITUTION:In a method preparing an analysis model by expressing an analysis object as a group of elements and setting the physical variable conditions for each element, the element of the analysis object is divided by combining a constant element distributing variables in an element constantly, a linear element changing the variable in one-dimensional function or in a function of higher, or a higher-degree element. The linear element adjacent to the constant element or the variable of the node of the higher degree element are set identical with the value of the variable of the constant element among the node of the linear element or the higher degree element, preparing the analysis model.
