Numerical analysis model data generating method for filling holes in a mesh

A non-transitory computer readable medium storing a computer program that causes a computer to execute a numerical analysis model data generating method, the method comprising:

• inputting three-dimensional shape data that defines a structure;
• segmenting the inputted three-dimensional shape data into three-dimensional polyhedral microscopic elements by using a three-dimensional mesh pattern, a mesh of the mesh pattern defined as an analytical unit;
• determining a ratio of a volume of a microscopic element of the polyhedral microscopic elements in the mesh to a volume of the mesh;
• comparing the ratio of the volume of the microscopic element with a predetermined maximum filing ratio;
• transforming the microscopic element having the ratio of the volume larger than the predetermined maximum filing ratio into a microscopic element without a hole by deleting data corresponding to the hole in the mesh;
• and
• providing as the numerical analysis model data a set of all the microscopic elements including the microscopic element without a hole.
