<p><P>PROBLEM TO BE SOLVED: To provide a computational grid forming device, a computational grid forming method and a program, for forming a high-quality computational grid by suppressing crush or deformation occurring when moving the computational grid. <P>SOLUTION: A computation space is divided into an object fixing area 51 that is an area closest to an object 60, a deformation area 55 that is an area distant from the object fixing area by just a prescribed number of grid points, and a buffer area 53 provided between the object fixing area 51 and the deformation area 55, and a movement vector of the grid is calculated by a different computation method in each area. A grid movement operation part 200 determines the movement vector such that a grid point moves together with the object in the object fixing area 51, calculates the movement vector by optional technique in the deformation area 55, and computes the movement vector such that the grid vectors of the above respective areas smoothly continue in the buffer area 53. In particular, in the buffer area 53, the movement vector may be computed by computation methods different in an edge part 531 and in a corner part 533. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
