Hexahedral finite element modeling method for controlling element size and storage medium therefor

A storage medium of a hexahedral finite element modeling system, comprising:

• a first program code for dividing one face of a hexahedral finite element into four uniform sections, and dividing a diagonally opposite face into sixteen uniform sections, thus modeling the finite element into a face-refined transition unit mesh module;
• a second program code for modeling the hexahedral finite element into an edge refined transition unit mesh module, which has two faces of the face-refined transition unit mesh module in common, and in which one edge of the finite element is divided into two uniform sections and a diagonally opposite edge is divided into four uniform sections;
• a third program code for modeling the hexahedral finite element into a vertex-refined transition unit mesh module, which has three faces of the edge-refined transition unit mesh module in common, and in which three faces meeting together at one node of the finite element are each divided into four uniform sections, and three faces meeting together at a diagonally opposite node are each partially divided into four uniform sections;
• a fourth program code for integrating the face-refined transition unit mesh module, edge-refined transition unit mesh module and vertex-refined transition unit mesh module into a single structure at their faces having the same meshed patterns;
• a fifth program code for displaying the structure of each of the face-refined transition unit mesh module, edge-refined transition unit mesh module and vertex-refined transition unit mesh module or the integrated structure of the element meshes in the form of a two- or three-dimensional image;
• a sixth program code for printing the structure of each of the face-refined transition unit mesh module, edge-refined transition unit mesh module and vertex-refined transition unit mesh module or the integrated structure of the element meshes, displayed in the form of the two- or three-dimensional image, on a paper, thus obtaining a printed image of the structure;
• a seventh program code for inputting, correcting and deleting a variety of numerical values of a target structure to be modeled into the face-refined transition unit mesh module, edge-refined transition unit mesh module and vertex-refined transition unit mesh module;
• and
• an eighth program code for storing data of the structure of the face-refined transition unit mesh module, edge-refined transition unit mesh module and vertex-refined transition unit mesh module.
