Simplified calculation of rHCT basis functions for an arbitrary splittingWeise, Michael 06 February 2015 (has links) (PDF)
Reduced Hsieh-Clough-Tocher elements are triangular C1-elements with only nine degrees of freedom. Simple formulas for the basis functions of reduced Hsieh-Clough-Tocher elements based on the edge vectors of the triangle have been given recently for a barycentric splitting. We generalise these formulas to the case of an arbitrary splitting point.

A note on the second derivatives of rHCT basis functionsWeise, Michael 29 October 2014 (has links) (PDF)
We consider reduced Hsieh-Clough-Tocher basis functions with respect to a splitting into subtriangles at the barycenter of the original triangular element.
This article gives a proof that the second derivatives of those functions, which in general may jump at the subtriangle boundaries, do not jump at the barycenter.

A note on the second derivatives of rHCT basis functions - extendedWeise, Michael 06 February 2015 (has links) (PDF)
We consider reduced Hsieh-Clough-Tocher basis functions with respect to a splitting into subtriangles at an arbitrary interior point of the original triangular element. This article gives a proof that the second derivatives of those functions, which in general may jump at the subtriangle boundaries, do not jump at the splitting point.
