With the consolidation of some duplicate code, this problem has been fixed. Internal code cleanup and optimization. Made logging more systematic. Length-scale calculation in 3D now much improved. Previously, this calculation was quite poor in some circumstances.
More work still needs to be done here.
Internal code clean up , including some additional state info that will soon improve point deletion, especially in 3D. Streamlined general mesh improvement algorithm via better decision-making about which points to try to smooth and which faces to try to swap in mesh improvement. Some speed improvement as a result, but intrinsically slow. Mesh improvement with approximately constant total mesh size . Better documentation for shared library use with sh-type shells . Documentation of command-line mesh optimization strings .
