PROBLEM TO BE SOLVED: To improve the accuracy or computation speed of analysis of a golf ball using a finite element method. SOLUTION: A model representing the golf ball is prepared on a computer, and computation is made by the finite element method using elements and nodes. At this time, the elements are made solid elements of hexahedron, the aspect ratio of the shape of each element is set not to be lower than 1.0 and not to be substantially higher than 6.5, and nodes are provided on the sides and the vertexes of the hexahedron of element.
