Abstract [en]

Smoothing improves the mesh quality by repositioning nodes while h-adaptive remeshing changes the topology of the mesh. The combination of these two schemes is indispensable when dealing with models with distorted elements and/or moving gradients in the solution. Different smoothing techniques for creating a mesh of high quality are studied. The quality of the mesh is quantified by a distortion metric. The adaptive remeshing procedure uses a generic error estimate for determining the size of new elements. The combined techniques are implemented for a graded finite element.
