Korotov, Sergey; Vatne, Jon Eivind The minimum angle condition for \(d\)-simplices. (English) Zbl 1446.65100 Comput. Math. Appl. 80, No. 2, 367-370 (2020). Summary: In this note we present a natural generalization of the minimum angle condition, commonly used in the finite element analysis for planar triangulations, to the case of simplicial meshes in any space dimension. The equivalence of this condition with some other mesh regularity conditions is proved.
