摘要

PPROBLEM TO BE SOLVED: To provide a boundary condition setting method in numerical analysis by a computer by which a highly accurate solution is obtained even when an arbitrary boundary shape, including a curved surface boundary and an oblique boundary is present in the numerical analysis. PSOLUTION: In the boundary condition setting method, a boundary value in a boundary-containing element is analyzed by using the interpolation function of the element, a partial simultaneous equation including an unknown is obtained by a program. Wherein, the unknown is applied to the value of a node (for example, potential) located outside the boundary so that the variation of a pan function being an integral over the boundary of the square of a difference between the boundary value calculated by using the interpolation function and a boundary value provided as the boundary conditions is zero. And a boundary condition setting system and its program are provided. PCOPYRIGHT: (C)2004,JPO

要解决的问题：提供一种在计算机进行数值分析的边界条件设置方法，即使在数值中存在包括曲面边界和倾斜边界的任意边界形状时，也可以通过该边界条件设置方法获得高精度的解决方案分析。

解决方案：在边界条件设置方法中，使用元素的插值函数分析包含边界的元素中的边界值，并通过程序获得包含未知数的局部联立方程。其中，将未知数应用于位于边界之外的节点的值（例如，电势），以使pan函数的变化在通过使用以下公式计算的边界值之间的差的平方的边界上成为整数插值函数和边界条件为零时提供的边界值。并提供了边界条件设置系统及其程序。
