[0] SPH SIMULATIONS OF A 2D DAM-BREAK FLOW AGAINST A VERTICAL WALL. GENERAL INFORMATION ON THE COLLECTION
https://doi.org/10.4121/14309240


1. Generalities

This dataset provides context information on the collection 'High-resolution SPH simulations of the 2D dam-break flow against a vertical wall' with referrer https://doi.org/10.4121/c.5353691; on the relationship between the companion datasets containing the output data at different resolutions (parameter H/dx); and on the software used to generate them. 

The companion output datasets are namely:
a) '[1] Highest-resolution SPH simulations of a 2D dam-break flow against a vertical wall. Output data for H/dx=6400, 82M fluid particles.' https://doi.org/10.4121/14309234
b) '[2] Upper-middle-resolution SPH simulations of a 2D dam-break flow against a vertical wall. Output data for H/dx=3200, 20M fluid particles.' https://doi.org/10.4121/14309171
c) '[3] Lower-middle-resolution SPH simulations of a 2D dam-break flow against a vertical wall. Output data for H/dx=1600, 5M fluid particles.' https://doi.org/10.4121/14309081
d) '[4] Lowest-resolution SPH simulations of a 2D dam-break flow against a vertical wall. Output data for H/dx=800, 1M fluid particles.' https://doi.org/10.4121/14308883

This dataset also includes: a rendering of the flow fields for each file in the output datasets above, for a rapid preview of their content; and the source code and license of the DualSPHysics suite used to generate the output datasets.

The file Commentary.pdf given in this one 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. 
Perusing that file first is strongly recommended.


2. Description of the content and naming convention

The file Commentary.pdf with why-and-how-to information on this collection of datasets.

The file ec025723b947f9d3af96ead3025393681b4fd1ed.zip is the archive of the unmodified DualSPHysics suite, including the source code and the license terms.

The file Meringolo.patch is a human readable file that details the changes applied to the original source code before generating the output datasets.

The file Meringolo_Def.xml is a template of the simulation input files containing user-defined parameters.

The file meringolo.sh is a script for a Unix shell showing the arguments given to the individual DualSPHysics executables.

The archive files with name Preview* and extension *.7z (12 items) group the flow-field snapshots according to the spatial resolution of the simulation and to the quantity shown (vel: velocity, den: density, pid: particle identification number). You can ignore notices on 'special feature...' overlaid to the frames: that feature has been implemented all over, hence it is not special any longer; see Section 2.2.1 of the collection's Commentary.pdf.

Including this README.txt this dataset contains 18 standalone files.
