Overlapping Schwarz Preconditioners for Isogeometric Collocation Methods Based on Generalized B-Splines

We study overlapping additive Schwarz (OAS) preconditioners for the solution of elliptic boundary value problems discretized using isogeometric collocation methods based on generalized B-splines (GB-splines). Through a series of numerical experiments, we demonstrate the <i>scalability</i>...

description We study overlapping additive Schwarz (OAS) preconditioners for the solution of elliptic boundary value problems discretized using isogeometric collocation methods based on generalized B-splines (GB-splines). Through a series of numerical experiments, we demonstrate the <i>scalability</i> of the proposed preconditioning strategy with respect to the number of subdomains, as well as its <i>robustness</i> with respect to the parameters of the isogeometric discretization.
