Versatility of the SPH method in the simulation of lava-environment interactions

Résumé

The Smoothed Particle Hydrodynamics (SPH) numerical method is relatively new compared to other more established methods, and thanks to the sustained research and the technological progress of computing hardware, is showing increasing viability and potential for extensive applications. Originally developed as a method for astrophysical studies, it is now applicable to many physical and technological contexts. Here, we will discuss the application of SPH to the simulation of lava flows and their interaction with natural and urban environments. We will show study cases simulated using the high performance SPH engine GPUSPH, which embeds the most advanced SPH model for lava simulation. The test cases cover interactions with natural topographies, rigid structures and compliant structures, and water basins. These elements constitute the basis to describe most lava eruption scenarios, opening up to a deeper understanding of the interaction processes and an enhanced evaluation of the risks associated with lava flows.
