I am using PolygonalMeshGenerator to generate a mesh. For my application it is import to keep the exact vertices of the boundary. So let polygon be a list of points. Then the call
PolygonalMeshGenerator(mesh, polygon, 0.05)
will put extra points on the boundary to achieve some Mesh quality criterion. This happens even when the set of points is already relatively dense.
So how can I keep the boundary clean so that the boundary mesh is exactly polygon?
