An augmented Lagrangian preconditioner for the magnetohydrodynamics equations at high Reynolds and coupling numbers

F Laakmann, PE Farrell, L Mitchell - SIAM Journal on Scientific Computing, 2022 - SIAM
The magnetohydrodynamics (MHD) equations are generally known to be difficult to solve
numerically, due to their highly nonlinear structure and the strong coupling between the …
