TL;DR: Computational advances enable the modeling of global geophysical processes to the scale of a kilometer and reveal unexpected insights into localized processes, such as subduction zone mechanics, thermal anomalies in the lower mantle, and the speed of movement of oceanic plates.

TL;DR: A new generation, parallel adaptive-mesh mantle convection code, Rhea, is described and benchmarked, demonstrating scalability to 122 880 compute cores and verifying correctness of the implementation.

TL;DR: In this article, a model of global mantle flow with plates is computed using adaptive finite elements, and compared to a variety of observational constraints, including a composite rheology with yielding, and incorporate details of the thermal buoyancy field.

TL;DR: In this article, a global model of mantle convection with plates is developed that is consistent with detailed constraints on the state of stress and strain rate from deep focus earthquakes, and the regions containing the M_W 8.3 Bolivia and M_w 7.6 Tonga 1994 events are considered in detail.

TL;DR: In this paper, the authors developed software tools to simulate finite strain, two-phase flow around a circular inclusion in a configuration that mirrors the experiments and found that the evolution of porosity is predominantly controlled by the porosity-weakening exponent of the shear viscosity and the poorly known bulk visco-ity.
