摘要
An analysis method using a finite element method includes: selecting an analysis domain to be analyzed; dividing the analysis domain into elements as calculation objects; creating a matrix of each element; integrating a general function term as a product of a Galerkin weight function and a general function; creating simultaneous equations, based on the sum of matrices of respective elements and the sum of values obtained by integrating the general function term, and obtaining a numerical solution from the simultaneous equations. In integrating the general function term, the concept of a nodal domain defined based on a result of discretization of a second-order differential term according to a Galerkin finite element method is introduced, and the general function term using a typical value of the element is integrated.
