Simple Mesh

Here, we consider generating rectangular domain nodes (2D) and cuboidal domain nodes (3D) by controlling the starting range and step size in each direction.

2D

Consider a rectangular area where the range in the x-direction is from 0 to 10 and in the y-direction from 0 to 6. The step size in the x-direction is 1, and in the y-direction, it is 2. Therefore, we can do:

pts = meshbuilder(0.0 : 1.0 : 10.0, 0.0: 2.0 : 6.0)

This way, we can obtain the results shown in the figure. The variable pts is an array where the first column contains the x-coordinates of all the nodes, and the second column contains the corresponding y-coordinates.

3D

pts = meshbuilder(0.0 : 1.0 : 10.0, 0.0: 2.0 : 6.0, 0.0 : 2.0 : 4.0)

MaterialPointGenerator.jl提供了一个非常便利的函数来导出三维点集以方便可视化:

savexyz(output_dir, pts)

其中output_dir您想要导出的路, pts是三维点集，我们可以设置为：

savexyz(joinpath(homedir(), "tmp.xyz"), pts)
