Abstract: 

Melt generation and migration are an important link between surface processes and the thermal and chemical evolution of the Earth's interior. However, due to the vastly different time and length scales of the motion of solid and molten rock, it is difficult to study these processes in a unified framework, especially in three-dimensional, global models. I will present the open source finite element code ASPECT, which simulates coupled magma/mantle dynamics using adaptively refined meshes. Applying adaptive mesh refinement to this type of problems is particularly advantageous, as the resolution can be increased in areas where melt is present and viscosity gradients are high, whereas a lower resolution is sufficient in regions without melt. Together with a high-performance, massively parallel implementation, this allows for high resolution, 3d, compressible, global mantle convection simulations coupled with melt migration.
