Performance of the HYMLS multilevel ILU preconditioner on 3D flow equations

Baars, Sven and van der Klok, Mark and Song, Weiyan and Thies, Jonas and Veldman, Arthur E. P. and Wubs, Fred W. (2019) Performance of the HYMLS multilevel ILU preconditioner on 3D flow equations. Computers and Mathematics with Applications. Elsevier. ISSN 0898-1221 (Unpublished)

This paper discusses the solution of the three dimensional, steady, incompressible Navier-Stokes equations using a fully coupled iterative approach. We discuss and demonstrate the advantages of avoiding time integration, and of the fully coupled incomplete LU (ILU) factorization (as opposed to block preconditioners trying to split the problem into scalar subsystems). The paper introduces the idea of skew-partitioning to overcome practical issues encountered in the recursive computation of the multi-level ILU on staggered grids.
