Multi-resolution technique represents a hot topic within the SPH research community. In the present work, we propose to extend the RHOD-SPH scheme derived in [1] to multi-resolution technique. Fine particles are concentrated in zones of interest and, thanks to the RHOD-SPH framework, no buffer regions are required. A dynamic refinement procedure is used to maintain fine particles where needed, e.g. in the free-surface region or close to solid boundaries. The formulation is validated for complex free-surface flows, showing a good agreement with both reference and single resolution results.

Abstract
Multi-resolution technique represents a hot topic within the SPH research community. In the present work, we propose to extend the RHOD-SPH scheme derived in [1] to multi-resolution technique. Fine particles are concentrated in zones of interest and, thanks to the RHOD-SPH framework, no buffer regions are required. A dynamic refinement procedure is used to maintain fine particles where needed, e.g. in the free-surface region or close to solid boundaries. The formulation is validated for complex free-surface flows, showing a good agreement with both reference and single resolution results.File in questo prodotto:
