Vector Extrapolation Methods Applied To Geometric Multigrid Solvers For Isogeometric Analysis
Abdellatif Mouhssine, Ahmed Ratnani, Hassane Sadok
In the present work, we study how to develop an efficient solver for the fast resolution of large and sparse linear systems that occur while discretizing elliptic partial different…
