Zienkiewicz-Zhu error estimators on anisotropic tetrahedral and triangular finite element meshes

Show other versions (1)

We consider a posteriori error estimators that can be applied to anisotropic tetrahedral finite element meshes, i.e. meshes where the aspect ratio of the elements can be arbitrarily large. Two kinds of Zienkiewicz-Zhu (ZZ) type error estimators are derived which are both based on some recovered grad...
