Multi-resolution technique represents a hot topic within the SPH research community. In the present work, we propose to adapt the RHOD-SPH scheme derived in [8] to multi-resolution technique, especially regarding the treatment of Riemann-based diffusive terms. The formulation is validated for both internal and free-surface flows, showing a good agreement with results obtained with single resolution.

Abstract
Multi-resolution technique represents a hot topic within the SPH research community. In the present work, we propose to adapt the RHOD-SPH scheme derived in [8] to multi-resolution technique, especially regarding the treatment of Riemann-based diffusive terms. The formulation is validated for both internal and free-surface flows, showing a good agreement with results obtained with single resolution. No splitting and coalescing procedures are considered, this topic being let to future works.File in questo prodotto:
