History
DualSPHysics1 is a Smoothed Particle Hydrodynamics (SPH) solver used to solve the fundamental equations of fluid dynamics, the Navier-Stokes equations. Among the modern SPH solvers available, there are many advantages to choosing DualSPHysics, most notably the optimization of the code for GPU parallel processing. Running the DualSPHysics code on a GPU vastly decreases solution times, thereby allowing high-resolution and/or large-domain cases to be executed efficiently. Researchers in the UMaine School of Earth and Climate Sciences and Climate Change Institute began using DualSPHysics v3.1 in 2014 to investigate the kinematics of icebergs. Since then, the DualSPHysics development team has added many useful features to the code which broaden the scope of scientific questions we can address using the SPH method. In particular, the addition of new boundary conditions, liquid + sediment physics, and fluid-structure interaction with Discrete Element Method systems have created research opportunities in the earth sciences.
Guidelines
The following guidelines are based on my experience working with the DualSPHysics code. My hope is that the points presented here will allow you to succeed in creating models which faithfully represent the systems you want to model, with minimal frustration. First things first, let's establish where you ought to look for answers to your DualSPHysics questions.
The DualSPHysics Wiki on GitHub
In 2018, the DualSPHysics project was moved to a GitHub repository. The Wiki section of the repository should be your go-to resource for all aspects of DualSPHysics, with the exception of model design. At the time of writing (March 2019), the preprocessing section of the Wiki lacks the detail of the XML_v4.0_GUIDE.XML_v4.0_GUIDE
