PROBLEM TO BE SOLVED: To provide a reproduction method which can easily reproduce a three-dimensional grid mesh that has its broken element due to the deformation of an analysis object during execution of the numerical analysis of a phenomenon causing deformation of the analysis object and therefore can improve the analysis accuracy and also to provide a device and a recording medium for execution of the said reproduction method. SOLUTION: A free curved surface generation part 1 fetches the data on an old mesh including a broken element from an old mesh data file 11 and generates the free curved surfaces approximating the lamination surface of old mesh elements arrayed in optional three directions in a three-dimensional space and stores the generated surface in a free curved surface data file 4. A free curved surface operation part 2 fetches the data from the file 4 and applies the operations (shape change, deletion and addition) to free curved surfaces in the three directions to eliminate the mutual interference of them and stores the obtained shape data on the free curved surfaces in a free curved surface data file 5. A mesh reproduction part 3 combines the free curved surfaces stored in the file 5 to generate a new mesh as an aggregate or hexahedron elements defining the intersections of intersecting lines of those curved surfaces, for example, and outputs the obtained data to a new mesh data file 12. |
