Hi;
I thought you would find this library interesting:

MESQUITE is a linkable software library that applies a variety of node-movement
algorithms to improve the quality and/or adapt a given mesh. Mesquite uses
advanced smoothing and optimization to:
Untangle meshes,
Provide local size control,
Improve angles, orthogonality, and skew,
Increase minimum edge-lengths for increased time-steps,
Improve mesh smoothness,
Perform anisotropic smoothing,
Improve surface meshes, adapt to surface curvature,
Improve hybrid meshes (including pyramids & wedges),
Smooth meshes with hanging nodes,
Maintain quality of moving and/or deforming meshes,
Perform ALE rezoning,
Improve mesh quality on and near boundaries,
Improve transitions across internal boundaries,
Align meshes with vector fields, and
R-adapt meshes to solutions using error estimates.
Mesquite improves surface or volume meshes which are structured, unstructured,
hybrid, or non-comformal. A variety of element types are permitted. Mesquite is
designed to be as efficient as possible so that large meshes can be improved.
