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.
