On Degenerating Tetrahedra Resulting from Red Refinements of Tetrahedral Partitions
Sergey Korotov, Michal Křı́žek · Numerical Analysis and Applications · 2021
Abstract We analyze red refinements of tetrahedral partitions and prove that the measure of degeneracy of some produced tetrahedra may tend to infinity if the refinements are constructed in an inappropriate way. The maximum angle condition is shown to be violated in these cases, as well.
