摘要

PPROBLEM TO BE SOLVED: To provide a boundary element analysis method and a boundary element analysis program, capable of coping with variety of a symmetric property to perform efficient analysis when performing the analysis by use of the symmetric property of an analysis target. PSOLUTION: Various kinds of data used for boundary element analysis inputted in step S101 are stored in step S102. At that time, at least state amount information wherein boundary element definition information for defining a boundary element of the analysis target and boundary element identification information for identifying a boundary element defined in each state amount of the boundary element are associated is stored. In step S103, a discretized boundary integral equation with a boundary value in an element point present on each the defined boundary element is generated by use of the various kinds of inputted data. Next, in step S104, an inputted boundary condition is substituted for the generated boundary integral equation, and an unknown quantity is arranged to obtain simultaneous equations. The obtained simultaneous equations are solved to find a value of the unknown quantity. PCOPYRIGHT: (C)2006,JPO&NCIPI

要解决的问题：提供一种边界元素分析方法和边界元素分析程序，当使用分析目标的对称属性进行分析时，该边界元素分析方法和边界元素分析程序能够应对多种对称属性以进行有效分析。

解决方案：在步骤S102中存储在步骤S101中输入的用于边界元素分析的各种数据。此时，至少存储状态量信息，在该状态量信息中，关联有用于定义分析对象的边界元素的边界元素定义信息和用于识别在边界元素的各状态量中定义的边界元素的边界元素识别信息。在步骤S103中，通过使用各种输入数据来生成在每个定义的边界元素上存在的元素点具有边界值的离散边界积分方程。接下来，在步骤S104中，将输入的边界条件替换为生成的边界积分方程，并且布置未知量以获得联立方程。对获得的联立方程进行求解，以找到未知量的值。
