PURPOSE:To form an optimum coordinate grid in accordance with a physical phenomenon by repeating the forming calculation of a coordinate grid while an analyzer is viewing an evaluation guidance showing the adaptability of the coordinate grid and the physical phenomenon to be analyzed. CONSTITUTION:After a numerical simulation 8 is executed by using an initial coordinate, a parameter is set to form the optimum coordinate lattice with respect to the result of the simulation. The parameter designates a weight function and an evaluation function for controlling the array of the coordinates. When the values of the evaluation functions significantly differ at every coordinate, the coordinate grid so formed and calculated that the value integrated by the whole grid volume is the smallest. An analyzer judges whether to repeat the guidance or not. When the guidance is to be repeated, the weight function and the evaluation function is corrected and added, and when the guidance is to be completed, the result of the coordinate grid is outputted. |
