    • A Geometric Toolbox for Tetrahedral Finite Element Partitions 

      Brandts J.; Korotov S.; Křížek M. (Efficient Preconditioned Solution Methods for Elliptic Partial Differential Equations, 2011-12-31)
      In this work we present a survey of some geometric results on tetrahedral partitions and their refinements in a unified manner. They can be used for mesh generation and adaptivity in practical calculations by the finite ...
    • Local nonobtuse tetrahedral refinements around an edge 

      Korotov S.; Křížek M. (Applied Mathematics and Computation, 2013-12-31)
      In this note we show how to generate and conformly refine nonobtuse tetrahedral meshes locally around and towards an edge so that all dihedral angles of all resulting tetrahedra remain nonobtuse. The proposed technique can ...
