Title: Method for preparing coordinate lattice
Inventor: MARUYAMA AKIHISA
IPC: G06F17/50
Filed: 1988-03-04
Abstract: PURPOSE:To collect a lattice near a boundary by successively checking the moving quantity of a lattice point and proceeding the calculation while correction is added. CONSTITUTION:Each time k-th order approximate coordinates are obtained, it is judged whether or not the k-th order approximate coordinates are in a prescribed area viewed from the order approximate coordinates concerning respective lattice points and when the coordinates exceed the prescribed area, the k-th order approximate coordinates of the lattice point is corrected so as to be in a prescribed area. Namely, by limiting the moving quantity of the coordinate lattice in the prescribed area, it is eliminated that the coordinate lattice becomes the value significantly different from the coordinate lattice of the front step. Thus, at the time of the solution of a linear equation system, the overflow does not occur and the coordinate lattice can be prepared.
