| 摘 要： | 为了提高ANSYS求解二维无界静电场的精确度,提出映射法.它是采用复指数函数,将无穷远边界线映射成一点,从而将一条边界线敞开的矩形边界的二维无界静电场,映射到其对应的二维有界静电场,再应用ANSYS求解.由于有界场的边值问题与无界场的边值问题相同,故有界场中某点的ANSYS解就是无界场中对应点的解.理论和计算的结果表明:映射法显著地提高了ANSYS求解二维无界静电场的精确度,并加快了计算速度. |

| Abstract: | In order to elevate the precision of applying ANSYS to solve a two-dimensional unbounded electrostatic field, a mapping method is presented. The mapping method, means in the domain of ANSYS calculating to apply complex exponential function to establish a mapping of a two-dimensional unbounded electrostatic field of which artificial boundaries of ANSYS is rectangle with one side open, the two-dimensional bounded electrostatic field. Then the two-dimensional bounded electrostatic field is calculated by ANSYS;so that the two-dimensional unbounded electrostatic field is solved. The results of theory and ANSYS calculation show that the mapping method obviously elevates the precision of applying ANSYS to solve a two-dimensional unbounded electrostatic field, and accelerates the calculating speed. |
