OpenFOAM Applications in Volcanology

Hosting Institution:

Istituto Nazionale di Geofisica e Vulcanologia (INGV), Italy

    Description:

    The Geo-INQUIRE Ch-OpenFOAM service includes a suite of OpenFOAM based solvers and libraries for volcanological and geophysical applications, optimized in the framework of ChEESE for HPC usage.

    OpenPDAC is a multiphase Eulerian-Eulerian-Lagrangian solver built upon the multiphaseEulerFoam native solver, customized for compressible, turbulent volcanic gas-particle mixtures. It comes with automatic workflows for High Performance Computing simulations of explosive volcanic eruptions over complex 3D topographies.

    ASHEE is a compressible fluid-dynamic model developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes.

    MagmaFOAM is a modular framework for the simulation of magmatic systems based on OpenFOAM. It incorporates models for solving the dynamics of multiphase, multicomponent magmatic systems and several benchmarks. MagmaFOAM sets a robust framework for in-house and community model development, testing and comparison.

    These flagship codes will be made available through physical TA (testing models on HPC infrastructures, running scientific applications) at INGV. Specifically, OpenPDAC, and MagmaFOAM are open-source ChEESE volcano dynamics simulation codes and will also be available through VA.

    TAs will offer computer resources provided in-kind by INGV (Pisa Department) on the Vesuvio cluster (7 nodes x 64 AMD cores, interconnection Infiniband 100 Gbps, 3TB RAM: 30TB storage).

    New OpenFOAM-based applications can be developed and made available during the course of the project. TAs can also be focused on new application development. 3 accesses are foreseen, each lasting three weeks.

    Target community/ Users:

    Researchers (of any level); Students (graduate).
