Transform before linearizing: robust Newton methods for singular -Laplace and -Stokes equations
Gonzalo G. De Diego, Fortino Garcia, Georg Stadler +1
For , the -Laplace equation and its -Stokes generalization are difficult to solve numerically. Newton's method converges rapidly only close to the solution, with itera…
Numerical approximation of viscous contact problems applied to glacial sliding
Gonzalo G. de Diego, Patrick E. Farrell, Ian J. Hewitt
Viscous contact problems describe the time evolution of fluid flows in contact with a surface from which they can detach and reattach. These problems are of particular importance i…
On the finite element approximation of a semicoercive Stokes variational inequality arising in glaciology
Gonzalo G. de Diego, Patrick E. Farrell, Ian J. Hewitt
Stokes variational inequalities arise in the formulation of glaciological problems involving contact. We consider the problem of a two-dimensional marine ice sheet with a grounding…
