[0] SPH simulations of a 2D dam-break flow against a vertical wall. General information on the collection

This dataset is the entry point to the simulations contained in the collection "High-resolution SPH simulations of the 2D dam-break benchmark solution by Meringolo et al., 2019" with referrer https://doi.org/10.4121/c.5353691Perusing this dataset first is strongly recommended. It provides the context information on the collection, how the data have been generated, how they can be reproduced/ accessed/used, how they are named and organized in this collection. It also provides a redistribution of the DualSPHysics software suite used to generate the data.The file Commentary.pdf in this dataset provides information on the generalities of the collection (physics, modelling, solver), on the test case (the dam-break flow impinging on a vertical wall), on the simulation datasets (aim, possible usages, creation and content, access, decompression, etc.), and on the research context. Reading that file first is strongly recommended.The companion datasets, then, contain the output results for values of the resolution parameter H/dx=800, 1600, 3200, 6400, leading to simulations with 1M, 5M, 20M, 82M fluid particles, as specified in the names of the datasets.This one dataset also includes the images of the flow fields for each file in the output datasets above; users can preview their content and evaluate which files to download and inspect avoiding bulk downloads.When using this dataset, please cite the overarching collection instead: Lipari, Giordano; Vuik, Cornelis (2021): High-resolution SPH simulations of a 2D dam-break flow against a vertical wall. 4TU.ResearchData.
