Abstract: A triangulated mesh generating method includes a first step of capturing data on triangulated mesh generated on the surface of a material in a computer and sequentially generating the tetrahedral mesh based on the surface triangulated mesh by using the computer, a second step of capturing the data on the tetrahedral mesh generated by the first step and dividing refining the tetrahedral mesh, and a third step of capturing the data on tetrahedral mesh generated by the second step and reducing and simplifying the number of tetrahedral meshes.

Abstract: A finite-element analyzing system executable by a computer includes an analyzing-condition setting unit that captures data on a solid model of a product and sets an analyzing condition, a high-density tetrahedral mesh generating unit that captures the solid model and the analyzing condition and adds an identification sign to an element, to which the analyzing condition is set, based on at least a setting element size, thereby generating a tetrahedral mesh with high density, a multi-resolution tetrahedral mesh generating unit that captures the tetrahedral mesh which is generated by the tetrahedral mesh generating unit and additionally has the identification sign, and a finite-element analyzing unit 4 that captures the tetrahedral mesh with multi-resolution which controls the resolution generated by the multi-resolution tetrahedral mesh generating unit and performs the finite-element analysis by using the analyzing condition.
