SUMMARY:3D Bézier Guarding: Boundary-Conforming Curved Tetrahedral Meshing
DESCRIPTION:Payam Khanteimouri and Marcel Campen (Osnabrück University)\n\
 nWe present a method for the generation of higher-order tetrahedral meshes
 . In contrast to previous methods, the curved tetrahedral elements are gua
 ranteed to be free of degeneracies and inversions while conforming exactly
  to prescribed piecewise polynomial surfaces, such as domain boundaries or
  material interfaces. Arbitrary polynomial order is supported. Algorithmic
 ally, the polynomial input surfaces are first covered by a single layer of
  carefully constructed curved elements using a recursive refinement proced
 ure that provably avoids degeneracies and inversions. These tetrahedral el
 ements are designed such that the remaining space is bounded piecewise lin
 early. In this way, our method effectively reduces the curved meshing prob
 lem to the classical problem of linear mesh generation (for the remaining 
 space).\n\nRegistration Category: Full Access, Enhanced Access, Trade Exhi
