Vanka-smoothed shifted Laplacian multigrid preconditioners for the Helmholtz equations

Rachel Yovel, Yunhui He, Eran Treister

We present an improved multigrid preconditioner for the acoustic Helmholtz equation with enhanced scalability. Standard multigrid fails to converge for the Helmholtz equation, and…

A SIMPLE-Based Preconditioned Solver for the Direct-Forcing Immersed Boundary Method

Rachel Yovel, Eran Treister, Yuri Feldman

We present a robust and scalable solver for direct-forcing immersed boundary simulations, based on a preconditioned SIMPLE algorithm. The method applies block elimination to the pr…
