Maximum angle condition for n-dimensional simplicial elements

In this paper the Synge maximum angle condition for planar triangulations is generalized for higher-dimensional simplicial partitions. In addition, optimal interpolation properties are presented for linear simplicial elements

On Synge-type angle condition for d-simplices

in interpolation theory and further used in finite element analysis and applications for triangular and later also for tetrahedral finite element meshes. In this paper we present some of its generalizations to higher-dimensional

The maximum angle condition is not necessary for convergence of the finite element method

We show that the famous maximum angle condition in the finite element analysis is not necessary to achieve the optimal convergence rate when simplicial finite elements element approximations may converge even thoug...

Generalization of the Zlámal condition for simplicial finite elements in Rd

The famous Zlámal's minimum angle condition has been widely used for construction of a regular family of triangulations (containing nondegenerating triangles) as well as in convergence proofs for the finite element method in 2d. In this pape...

Strong Regularity of a Family of Face-to-Face Partitions Generated by the Longest-Edge Bisection Algorithm

We examine the longest-edge bisection algorithm that chooses for bisection the longest edge in a given face-to-face simplicial partition of a bounded polytopic domain in Rd. Dividing this edge at its midpoint, we define a locally refined par...
