An optimally convergent smooth blended B-spline construction for semi-structured quadrilateral and hexahedral meshes
Kim Jie Koh, Deepesh Toshniwal, Fehmi Cirak
Easy to construct and optimally convergent generalisations of B-splines to unstructured meshes are essential for the application of isogeometric analysis to domains with non-trivia…
