High-resolution SPH simulations of a 2D dam-break flow against a vertical wall

This collection contains simulations at four spatial resolutions of the benchmark solution of the <b>2D dam break impinging against a vertical wall</b> used by D.D. Meringolo, S. Marrone, A. Colagrossi and Y. Liu. See "A dynamic δ-SPH model: how to get rid of diffusive parameter tuning" in Computers and Fluids, 2019, 179:334-355 (see References below). <br>The simulations implement a <b>Smoothed Particle Hydrodynamics methodology for weakly compressible flow</b>. The simulations in the individual datasets have spatial resolutions of the initial water column of 800, 1600, 3200 and 6400 particles, leading to total fluid-particle counts from 1M to 82M. The solver used is DualSPHysics 5.0 and the simulations have been performed on compute-capable GPUs.<br>Weakly compressible SPH is a computationally intensive and computationally demanding technique. Obtaining high-resolution data sets can be either difficult, impractical or unaffordable for many scholars and practitioners. <br><br>This collection provides data of an established benchmark usable, among other uses, for dissemination, visualisation, refined or extended `hot starts', comparisons of behaviours and results after different parameter settings and across different solvers. <br><br>This collection gathers five datasets. It is highly recommended to get started with the file <b>Commentary.pdf</b> distributed in the entry-point dataset "<b>[0] SPH simulations of a 2D dam-break flow against a vertical wall. General information on the collection</b>" at https://doi.org/10.4121/14309240. <br>The References below contain a link to a YouTube playlist rendering the fields of flow quantities at the dataset resolutions.<br><br>
