Research Note Abstract
We propose a new hexahedral mesh optimization technique that is based on the smoothing of the local frame system embedded in each hexahedral element. This smoothing process can be formulated as a quadratic optimization problem that can be solved efficiently. We have applied this technique for the improvement of the quality of a number of hexahedral meshes.
