• On Dihedral Angle Sums of Prisms and Hexahedra 

      Korotov, Sergey; Vatne, Jon Eivind (Journal article; Peer reviewed, 2023)
      Various angle characteristics are used (e.g. in finite element methods or computer graphics) when evaluating the quality of computational meshes which may consist, in the three-dimensional case, of tetrahedra, prisms, ...
    • Preserved Structure Constants for Red Refinements of Product Elements 

      Vatne, Jon Eivind; Korotov, Sergey (Journal article; Peer reviewed, 2021)
      In this paper we discuss some strategy for red refinements of product elements and show that there are certain structure characteristics (d-sines of angles formed by certain edges in the initial partition) which remain ...
