Anisotropic Delaunay Mesh Generation [PDF]
SIAM Journal on Computing, 2015 Summary: Anisotropic meshes are triangulations of a given domain in the plane or in higher dimensions, with elements elongated along prescribed directions. Anisotropic triangulations are known to be well suited for interpolation of functions or solving PDEs.

Reducing noise in moving-grid codes with strongly-centroidal Lloyd mesh regularization [PDF]
, 2015 A method for improving the accuracy of hydrodynamical codes that use a moving Voronoi mesh is described. Our scheme is based on a new regularization scheme that constrains the mesh to be centroidal to high precision while still allowing the cells to move
