Adaptive volcanic modelling using Discontinuous Galerkin Methods

Since the Eyjafjallajökull eruption in 2010, the volcanic modelling community has been focused on improving the prediction of ash dispersion and simulation of eruptive columns. While many new and powerful numerical methods have been developed for Computational Fluid Dynamics (CFD) and Atmospheric Modelling, very few have been integrated into models for volcanic eruptions.

We are developing a new volcanic plume model based on Discontinuous Galerkin Methods including Adaptive Mesh Refinement (AMR) techniques to ensure efficient and high-resolution simulations. 

The current research focuses on implementing adequate limiting/diffusion for gas dynamics and correct error indication for mesh refinement.
