Adaptive geometric multigrid for the mixed finite cell formulation of Stokes and Navier-Stokes equations
S. Saberi, G. Meschke, A. Vogel
Unfitted finite element methods have emerged as a popular alternative to classical finite element methods for the solution of partial differential equations and allow modeling arbi…

A restricted additive Vanka smoother for geometric multigrid
S. Saberi, G. Meschke, A. Vogel
The solution of saddle-point problems, such as the Stokes equations, is a challenging task, especially in large-scale problems. Multigrid methods are one of the most efficient solv…
