A mesh generation method using PC graphic editor

In this paper it is discussed about the program which makes automatically the preprocessing data on the graphic editor of PC monitor. Three kinds of colors are used in order to make know a boundary_element, in_element, out_element. By initial mesh generation, three kinds of elements are made; the element with three nodes, four nodes, five nodes. The node of boundary element draw a vertical line to the boundary. At that time the element with three nodes is removed and the element with four nodes is changed to the element with four nodes. The domain graphic on this paper is compose of piecewise curves which has many lines and a hole. The data of element is written on the memory of PC computer. The program controls the memory address according to the change of element's quantity; disappearance and addition of element. All this work is operated on the PC computer.
