 An offline Eulerian-Lagrangian model for the simulation of volcanic fluids. The model solves the conservation equations of mass, momentum and energy for a Eulerian-Eulerian compressible multiphase mixture of gases and fine (up to mm size) particles, and the Lagrangian transport equations for coarser solid particles. The solver is based on the equations of the PDAC model, ported and optimised on the open-source OpenFOAM C++ toolbox for Computational Fluid Dynamics (CFD).
