Journal ArticleDOI
Underpinning tectonic reconstructions of the western Mediterranean region with dynamic slab evolution from 3‐D numerical modeling
TL;DR: In this paper, three disparate tectonic evolution scenarios are identified, each portraying slab rollback as the driving mechanism but with rollback starting from strongly different subduction geometries.
Journal ArticleDOI
Scalable robust solvers for unstructured FE geodynamic modeling applications: Solving the Stokes equation for models with large localized viscosity contrasts
T. Geenen,M. ur Rehman,Scott MacLachlan,Guus Segal,Cornelis Vuik,A. P. van den Berg,Wim Spakman +6 more
TL;DR: In this article, the authors investigate the use of a smoothed aggregation (SA) algebraic multigrid (AMG)-type solution strategy to construct efficient preconditioners for the Stokes equation.
Journal ArticleDOI
Pressure effect on forsterite dislocation slip systems: Implications for upper-mantle LPO and low viscosity zone
TL;DR: In this paper, the effect of pressure on olivine dislocation slip-system activities was investigated in a Deformation-DIA apparatus on pure forsterite (Fo100) single crystals, at P Â⩾Â5.7 GPa, temperature T Â∼Â1675 K, differential stress σ σ and specimen strain rates ( e ˙ ) by synchrotron X-ray diffraction and radiography, respectively.
Journal ArticleDOI
On iterative methods for the incompressible Stokes problem
TL;DR: It is observed that the approximation based on the pressure mass matrix gives h‐independent convergence, for both constant and variable viscosity, in the finite‐element method.
Journal ArticleDOI
Using open sidewalls for modelling self-consistent lithosphere subduction dynamics
TL;DR: In this article, the authors investigated the merits of using open boundaries for 2D modelling of lithosphere subduction and concluded that open boundaries in combination with intraplate stress conditions are to be preferred for modelling subduction evolution (rollback, stationary or advancing).
