Abstract:
A growing and etching simulation method for dividing a material to be grown or etched into cells of a fixed size, and predicting a surface shape of said material after carrying out the growing or etching for a time â€œTâ€ , said growing and etching simulation method using a modified cell model including growing or etching points and comprising:forming an initial section of the material with a single layer of open cells, wherein only the open cells are exposed to the growing or etching process; inputting information, including growing or etching points, into each open cell; computing a movement speed for the growing or etching points; moving the growing or etching points for a time increment, wherein moving the growing or etching points is determined according to the movement speed; and forming a new growing or etching section by rearranging the open cells exposed to the growing or etching, after moving the growing or etching points; and repeating the above steps on the re-arranged open cells until the sum of a time increment reaches the time (T).
