Generalization of the Zlámal condition for simplicial finite elements in ℝ d
MetadataShow full item record
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 paper we present and discuss its generalization to simplicial partitions in any space dimension. © 2011 Institute of Mathematics of the Academy of Sciences of the Czech Republic, Praha, Czech Republic.
