Robust and efficient primal-dual Newton-Krylov solvers for viscous-plastic sea-ice models
Yu-hsuan Shih, Carolin Mehlmann, Martin Losch +1
We present a Newton-Krylov solver for a viscous-plastic sea-ice model. This constitutive relation is commonly used in climate models to describe the material properties of sea ice.…
Robust multigrid techniques for augmented Lagrangian preconditioning of incompressible Stokes equations with extreme viscosity variations
Yu-hsuan Shih, Georg Stadler, Florian Wechsung
We present augmented Lagrangian Schur complement preconditioners and robust multigrid methods for incompressible Stokes problems with extreme viscosity variations. Such Stokes syst…
Advanced Newton Methods for Geodynamical Models of Stokes Flow with Viscoplastic Rheologies
Johann Rudi, Yu-hsuan Shih, Georg Stadler
Strain localization and resulting plasticity and failure play an important role in the evolution of the lithosphere. These phenomena are commonly modeled by Stokes flows with visco…
