Triangle: -r switch

The -r switch

Refines a previously generated mesh.
The mesh is read from a .node file and an .ele file. If -p is also used, a .poly file is read and used to constrain segments in the mesh. If -a is also used (with no number following), an .area file is read and used to impose area constraints on the mesh.
The iteration number of the new mesh is one greater than that of the old mesh.
