Accelerating the iterative solution of convection-diffusion problems using singular value decomposition
Giuseppe Pitton, Luca Heltai
The discretization of convection-diffusion equations by implicit or semi-implicit methods leads to a sequence of linear systems usually solved by iterative linear solvers such as G…

NURBS-SEM: a hybrid spectral element method on NURBS maps for the solution of elliptic PDEs on surfaces
Giuseppe Pitton, Luca Heltai
Non Uniform Rational B-spline (NURBS) patches are a standard way to describe complex geometries in Computer Aided Design tools, and have gained a lot of popularity in recent years…

On the Application of Reduced Basis Methods to Bifurcation Problems in Incompressible Fluid Dynamics
Giuseppe Pitton, Gianluigi Rozza
In this paper we apply a reduced basis framework for the computation of flow bifurcation (and stability) problems in fluid dynamics. The proposed method aims at reducing the comple…
