Adaptive geometric multigrid for the mixed finite cell formulation of Stokes and Navier–Stokes equations
Abstract The 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 arbitrary geometries without the need for a boundary‐conforming mesh. On the other hand, the efficient solution of the resultant system is a challenging …
