在Python中将大的不规则网格插入到另一个不规则网格中

import numpy as np
import matplotlib.pyplot as plt

# 定义大的不规则网格的边界和顶点坐标
big_grid_vertices = np.array([[0, 0], [0, 1], [1, 1], [1, 0]])
big_grid_boundary = np.array([[0, 0], [0, 1], [1, 1], [1, 0]])

# 定义小的不规则网格的边界和顶点坐标
small_grid_vertices = np.array([[0.2, 0.2], [0.2, 0.3], [0.3, 0.3], [0.3, 0.2]])
small_grid_boundary = np.array([[0.2, 0.2], [0.2, 0.3], [0.3, 0.3], [0.3, 0.2]])

# 将小的不规则网格插入到大的不规则网格中
big_grid_vertices = np.vstack((big_grid_vertices, small_grid_vertices))
big_grid_boundary = np.vstack((big_grid_boundary, small_grid_boundary))

# 可视化插入后的不规则网格
plt.plot(big_grid_boundary[:, 0], big_grid_boundary[:, 1], 'o-')
plt.show()
