Hierarchical Schur complement preconditioner for the stochastic Galerkin finite element methods
Bedřich Sousedík, Roger G. Ghanem, Eric T. Phipps
Use of the stochastic Galerkin finite element methods leads to large systems of linear equations obtained by the discretization of tensor product solution spaces along their spatia…
