Scalable multigrid methods for immersed finite element methods and immersed isogeometric analysis

F. de Prenter, C. V. Verhoosel, E. H. van Brummelen +4

Ill-conditioning of the system matrix is a well-known complication in immersed finite element methods and trimmed isogeometric analysis. Elements with small intersections with the…
