Fluid dynamic modelling is commonly used in the Earth Sciences for simulating a wide range of processes. OpenFOAM is an open-source computational fluid dynamics toolbox that has recently begun to be applied to study problems in the Earth Sciences. The software has a modular structure, with built-in tools to create 2D and 3D meshes and solvers for multiphase fluids, particles, and thermodynamics. 

This two day course aims to provide an introduction to numerical modelling using OpenFOAM.

During the first day, introductory lectures will cover: modelling approach in Earth Sciences and fluid-dynamics; conservation laws in different forms (Lagrangian, Eulerian, conservative, non-conservative); partial differential equations and numerical solutions. Some exercises to understand the accuracy and stability of the numerical schemes. At the end of the first day, there will be a poster session and all participants are invited to bring posters on their research.

The second day will be dedicated to hands-exercises on OpenFOAM, with an introduction to topics including mesh generation, initial and boundary conditions, running solvers, and visualizing and analyzing the results, followed by applications of OpenFOAM to various geologically relevant problems (e.g. diffusive processes, magma mixing, ash dispersion, magma ascent). Participants will be able to take these materials with them to use or modify for their own research. These hands-on activities will be followed by presentations on how OpenFOAM is currently being used in volcanology and a discussion of future research directions and applications.

People should come with their laptop and should have already installed openfoam to optimize the time (https://www.openfoam.com/download/)
