Extraction and application of super-smooth cubic B-splines over triangulations
Jan Grošelj, Hendrik Speleers
The space of cubic Clough-Tocher splines is a classical finite element approximation space over triangulations for solving partial differential equations. However, for such a…

-smooth isogeometric spline functions of general degree over planar mixed meshes: The case of two quadratic mesh elements
Jan Grošelj, Mario Kapl, Marjeta Knez +2
Splines over triangulations and splines over quadrangulations (tensor product splines) are two common ways to extend bivariate polynomials to splines. However, combination of both…
