PROBLEM TO BE SOLVED: To improve a calculating speed by selecting only indispensable one part among variables discretely describing a field as parameter variables. SOLUTION: All variables (the functions of a field) describing the state of a field are connected with the finite number of points discretely distributed to a space. Those representative central points are classified into several ways, and equations of motion in the same number as the total number of those variables should be used anywhere for deciding all the variables corresponding to those representative central points neither too much nor too little. Then, those equations are divided into groups by each number equal to the number of the variables corresponding to each representative central point, and treated in a batch as a constitution equation corresponding to those representative central points. The way of preparation of the constitution equation can be decided as necessary in the simulation. Then, the number of the parameter variables at the time of performing the inverse calculation of a matrix is reduced so that the number of times of repetition necessary for the calculation and a memory space can be saved. |
