A systematic strategy for simultaneous adaptive hp finite element mesh modification using nonlinear programming

Adaptive refinement usually involves refining or enriching a fraction of mesh elements by one level based on a cut-off criterion, requiring several costly intermediate solutions before a mesh that yields an acceptable solution is obtained. We avoid this by formulating and solving the mesh design pro...
