A two-level preconditioner for discontinuous virtual element methods with irregular subdomains
Juan G. Calvo, César Herrera
We introduce and analyze a two-level overlapping additive Schwarz preconditioner for discontinuous Galerkin discretizations of virtual element spaces on general polygonal meshes in…

Coarse spaces for virtual element methods on irregular 3D subdomain decompositions
Ana Aguilar-Pineda, Luis F. Amey, Adrian Angulo-Paniagua +1
We present a two-level overlapping Schwarz preconditioner for three-dimensional problems discretized with the Virtual Element Method. Our approach handles general polyhedral meshes…
