# output01* is just the distribution of vertices without connectings as Delaunay triangles
|
|
# output02* connect the vertices as a Delaunay triangulation
|
|
# output03* is the same as output02 except the resoltion is reduced from 0.1 to 0.05

# output04* variable resolution mesh with target edge length defined in input_resolution_1.mlgi

# output05* variable resolution mesh with target edge length defined in input_resolution_2.mlgi
