A geometric mesh smoothing algorithm related to damped oscillations [PDF]

, 2014
We introduce a smoothing algorithm for triangle, quadrilateral, tetrahedral and hexahedral meshes whose centerpiece is a simple geometric triangle transformation. The first part focuses on the mathematical properties of the element transformation.
