图4 二维近场范围的均匀离散化[48]与面积修正[77]

Fig.4 Uniform discretization of horizon (a)[48] and area correction (b)[77] in 2D ( k —center point, Δx—size of uniform grid, i—material point xi, j—material point xj. Red stars are those with cells inside the neighborhood of i, brown triangles are those located inside the neighborhood of i, but with a cell having only a partial overlapping with the neighborhood of i, magenta squares are those located outside the neighborhood of i, with a nonzero overlapping between their cells and the neighborhood of i, blue points are those with cells outside the neighborhood of i)
