Polygon

Note

All example files can be found at assets/2d_nid https://github.com/LandslideSIM/MaterialPointGenerator.jl.

First, we obtained the .stl and .msh files of the model through Gmsh. The .msh file is used to identify the partition information within the model.

using MaterialPointGenerator

src_dir     = joinpath(@__DIR__, "assets/2d_nid")
stl_file    = joinpath(src_dir , "2d_nid.stl")
msh_file    = joinpath(src_dir , "2d_nid.msh")
nid_file    = joinpath(src_dir , "2d_nid.nid")
output_file = joinpath(src_dir , "2d_nid.xy")

polygon2particle(stl_file, msh_file, output_file, nid_file, 0.001, verbose=true)

Note that this will generate two files, namely .nid and .xy. We can visualize this result to obtain the following outcome:

In this example, we have a total of three partitions. A partially enlarged image:
