Therefore, we employ the abstraction of geometries as local-functions bound to a grid element, and the abstraction of a grid as connectivity of elements together with a grid-function that can be localized to the elements to provide element local parametrizations of the curved surface.</p> Simon Praetorius, Florian Stenger Copyright (c) 2022 Archive of Numerical Software https://journals.ub.uni-heidelberg.de/index.php/ans/article/view/75917 Wed, 09 Feb 2022 00:00:00 +0100
