PROBLEM TO BE SOLVED: To provide a finite element method direct calculation program and analysis method, capable of accurately visualizing and outputting a unique function by directly calculating and determining a rigidity matrix K and a mass matrix M in a short time almost without error by giving data even in a calculation using high-order elements while eliminating a work for assigning local numbers to nodes of each element from a data input work in data input of element division. SOLUTION: In the analysis method of the program for forming a numerical model of an analysis object by finite element method, performing numerical analysis thereto and visualizing the analysis result, the rigidity matrix K and the mass matrix M determined from a basis function of the finite element method are directly calculated, whereby a unique value and a unique function of the Laplacian unique value problem of a given area are determined.
