摘要

Two centerlines each of which goes through the center of a surface and is parallel to one of the coordinate axes are considered for each surface constituting a cell. If one of the centerlines intersects a boundary, a line which goes through the intersection and is orthogonal to the centerline is approximated as a new boundary. If a boundary intersects with each of the two centerlines, an orthogonal line expressed by each of two lines which is obtained by crossing each of the two centerlines parallel to each different coordinate axis and a boundary is approximated as a new boundary. Thus, the new boundary is expressed by each part of these orthogonal lines toward the centerline from their intersection.
