    • Efficient quadrature rules for subdivision surfaces in isogeometric analysis 

      Barendrecht P.; Kosinka J.; Barton M. (Computer Methods in Applied Mechanics and Engineering, 2018-10)
      We introduce a new approach to numerical quadrature on geometries defined by subdivision surfaces based on quad meshes in the context of isogeometric analysis. Starting with a sparse control mesh, the subdivision process ...
    • On numerical quadrature for $C^1$ quadratic Powell-Sabin 6-split macro-triangles 

      Barton M.; Kosinka J. (Journal of Computational and Applied Mathematics, 2018-08-01)
      The quadrature rule of Hammer and Stroud [16] for cubic polynomials has been shown to be exact for a larger space of functions, namely the $C^1$ cubic Clough-Tocher spline space over a macro-triangle if and only if the ...
