Hanging nodes for higher-order Lagrange finite elements
Examples and Counterexamples, 2021 We report in this work an extension of hanging nodes theory for Lagrange elements to higher-order elements. Concrete values of the constants that appear in the applications are also provided.

C and C0 hp-finite elements on d-dimensional meshes with arbitrary hanging nodes
Finite Elements in Analysis and Design, 2021 Abstract In this paper, the construction of Ck basis functions is proposed for paraxial d-dimensional rectangular meshes with arbitrary hanging nodes and arbitrary polynomial degree distributions. The construction is based on the large-support approach introduced in [1] for C0 basis functions in 2D and uses hierarchical tensor-product shape functions

Procedia Engineering, 2012 AbstractThis paper studies highly accurate algorithm for membrane vibration problem. Based on the theory of theinterpolation post-processing, this paper establishes a scheme of bi-quadratic interpolation post-processing of bilinearrectangular element on a locally refined mesh with hanging nodes. And the resulting solution is verysatisfactory.

ACM Transactions on Mathematical SoftwareIn this work, Nédélec elements on locally refined meshes with hanging nodes are considered. A crucial aspect is the orientation of the hanging edges and faces. For non-orientable meshes, no solution or implementation has been available to date. The problem statement and corresponding algorithms are described in great detail.

Modeling glacial and fluvial landform evolution at large scales using a stream-power approach [PDF]
Earth Surface Dynamics, 2021 Modeling glacial landform evolution is more challenging than modeling fluvial landform evolution. While several numerical models of large-scale fluvial erosion are available, there are only a few models of glacial erosion, and their application over long

Adaptive Semi-Structured Mesh Refinement Techniques for the Finite Element Method
Applied Sciences, 2021 The adaptive mesh techniques applied to the Finite Element Method have continuously been an active research line. However, these techniques are usually applied to tetrahedra. Here, we use the triangular prismatic element as the discretization shape for a
