A minimal stabilization procedure for Isogeometric methods on trimmed geometries
Annalisa Buffa, Riccardo Puppi, Rafael Vázquez
Trimming is a common operation in CAD, and, in its simplest formulation, consists in removing superfluous parts from a geometric entity described via splines (a spline patch). Afte…

Multipatch Approximation of the de Rham Sequence and its Traces in Isogeometric Analysis
Annalisa Buffa, Jürgen Dölz, Stefan Kurz +3
We define a conforming B-spline discretisation of the de Rham complex on multipatch geometries. We introduce and analyse the properties of interpolation operators onto these spaces…
