FDTD Mesh-Generating and Visual Realization Based on Triangle-Patch

In view of the difficult problem of Yee cell modeling in electromagnetic numerical calculation by Finite-Difference Time-Domain,this paper proposed a method of switching from triangle-patch model to Yee cell model to judge where is the center of Yee cells,and then carried out FDTD calculation according to the outputs.The results proved that this method can achieve FDTD auto dissection of entity with grid accurately.The vision of the dissection of entity with grid is achieved by OpneGL technique,and it can improve the ability of FDTD electromagnetic simulation effectively.
