A high order multigrid-preconditioned immersed interface solver for the Poisson equation with boundary and interface conditions
James Gabbard, Andrea Paris, Wim M. van Rees
This work presents a multigrid preconditioned high order immersed finite difference solver to accurately and efficiently solve the Poisson equation on complex 2D and 3D domains. Th…
