Stabilized isogeometric formulation of the Stokes problem on overlapping patches
Xiaodong Wei, Riccardo Puppi, Pablo Antolin +1
We present a novel stabilized isogeometric formulation for the Stokes problem, where the geometry of interest is obtained via overlapping NURBS (non-uniform rational B-spline) patc…
A cut finite element method for the Darcy problem
Riccardo Puppi
We present and analyze a cut finite element method for the weak imposition of the Neumann boundary conditions of the Darcy problem. The Raviart-Thomas mixed element on both triangu…
Two mixed finite element formulations for the weak imposition of the Neumann boundary conditions for the Darcy flow
Erik Burman, Riccardo Puppi
We propose two different discrete formulations for the weak imposition of the Neumann boundary conditions of the Darcy flow. The Raviart-Thomas mixed finite element on both triangu…
Isogeometric discretizations of the Stokes problem on trimmed geometries
Riccardo Puppi
The isogeometric approximation of the Stokes problem in a trimmed domain is studied. This setting is characterized by an underlying mesh unfitted with the boundary of the physical…
Overlapping Multi-Patch Isogeometric Method with Minimal Stabilization
Pablo Antolin, Annalisa Buffa, Riccardo Puppi +1
We present a novel method for isogeometric analysis (IGA) to directly work on geometries constructed by Boolean operations including difference (i.e., trimming), union and intersec…
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…
