It can divide mesh arbitrarily, give the numberofelement and node automatically.
只需输入控制参数，可自动任意划分网格，自动进行单元及结点编号。

It shows that the numberofelement can be greatly reduced while the accuracy is acceptable and thus the time solving the problem is saved.
结果表明在精度满足要的前堤下，可以减少单元划分，大幅度减少计算时间。

Under the optimization constraints of the numberofelement, the aperture and the minimum element spacing, the MGA has been utilized to reduce the peak sidelobe level (PSLL) of the array.
