Knots in the mesh

[behroozkarami]

Dear All,

After meshing the tessellation I get a (2D) mesh, though correct, there exist some points look like knots in the mesh exhibiting a relatively large number of elements (with small sizes) created around those points which look not to be necessary.
Was wondering how can I resolve those knots?
For meshing I use the simple command: neper -M d.tess -elttype tri
Thank you very much

This can be avoided by switching regularization on in -T (-reg 1) to remove the small edges, and if necessary, by increasing the value of the "progression factor" (-pl 10 or more) in -M.
