Parallel Algorithms for Adaptive Mesh Refinement [PDF]
SIAM Journal on Scientific Computing, 1997 Summary: Computational methods based on the use of adaptively constructed nonuniform meshes reduce the amount of computation and storage necessary to perform many scientific calculations. The adaptive construction of such nonuniform meshes is an important part of these methods.

Computer Assisted Methods in Engineering and Science, 2017 This paper deals with hp-type adaptation in the discontinuous Galerkin (DG) method. The DG method is formulated in this paper with a non-zero mesh skeleton width, which leads to a version of the method called in this paper the interface discontinuous ...

Cost Minimizing Local Anisotropic Quad Mesh Refinement [PDF]
, 2020 Quad meshes as a surface representation have many conceptual advantages over triangle meshes. Their edges can naturally be aligned to principal curvatures of the underlying surface and they have the flexibility to create strongly anisotropic cells ...

Adaptive mesh refinements for thin shells whose middle surface is not exactly known [PDF]
, 2008 A strategy concerning mesh refinements for thin shells computation is presented. The geometry of the shell is given only by the reduced information consisting in nodes and normals on its middle surface corresponding to a coarse mesh.
