SPH MODELING

Numerical modeling represents a viable alternative for the description of natural phenomena to expensive, long running physical model tests. When dealing with water, Smoothed Particle Hydrodynamics (SPH) technique is among the most suitable numerical approaches to tackle undergoing large deformations and complex geometries.

As a meshless and Lagrangian method, SPH has become increasingly popular in recent years as a novel technique to model violent hydrodynamics in wave breaking, wave-structure interaction, and floating objects. SPH finds room to deal with more and more industrial applications and engineering design. Recently, SPH has been successfully applied in the context of energy harvesting and coastal defense, currently representing hot topics of great interest in light of the ongoing energy market trends and global warming.  

DUALSPHYSICS

The DualSPHysics code has been developed to use SPH for real engineering problems. DualSPHysics is open source and can be freely downloaded from the website www.dual.sphysics.org. The code can be proposed as a complementary tool to physical model experiments for the preliminary design of structures exposed to the action of violent flows.

The code comes with dedicated pre- and post-processing software which can use a whole range of different input files for the geometries including CAD, STL, PLY files, etc., making setting up simulations straightforward. Advanced post-processing tools enable users to measure the physical magnitudes of any flow property at arbitrary locations in the domain.
