Description

This SIG brings together researchers from across the UK that use or are interested in applying meshless methods to their fluid dynamics (or related) problems, with a particular emphasis on smoothed particle hydrodynamics (SPH). Domains covered by this SIG are varied, ranging from all aspects of engineering through to astrophysics.

Future SIG Events

Please refer back for news about future SPH SIG meetings, both virtual and in-person.

The SIG's mailing list is handled using an external resource, if you would like to be added to this then please contact Stephen Longshaw. 

Upcoming Events

The SPH SIG organises regular seminar events where SPH researchers give short talks about various aspects of their use and development of the SPH method. It also organises longer, more in-depth talks called deep-dives which see hour-long lectures from prominent SPH researchers both UK based and international.

Where possible, all SPH SIG talks are recorded and added to our YouTube channel.

SPH SIG Virtual Seminar Series

The next SPH-SIG seminar will be held virtually on the afternoon of the 28th of September 2022.

Details and how to register will be posted here in the coming weeks.

SPH SIG Deep-Dives

The SPH-SIG will be organising more deep-dive talks in the future. For the moment, you can revisit our past talks via YouTube.

The current committee is as follows:

• Dr Stephen Longshaw (UKRI-STFC): Chair

SIG Meeting 5: The Ogden Centre, Hosted by Durham University - 28th - 29th November 2019

This final meeting of the UK Fluids Network sponsored series saw talks spread over two days from the UK's astrophysics and engineering communities. Both presented the best of the SPH outputs from each community, highlighting achievements of the method to date and where its challenges lie in the future. Download a full report of the meeting here.

SIG Meeting 4: National Structural Integrity Research Centre, Granta Centre, Hosted by Brunel University London - 10th July 2019

This meeting saw the SPH SIG present the current state of the art for SPH modelling, as well vendors of commercial and open-source SPH software describing what it can be practically used for. Download a full report of the meeting here.

A number of presentations given at the meeting have also been released for download by their authors:

• Tom De Vuyst (Brunel University): Application of SPH to solid mechanics problems
• Paul Groenenboom (ESI Group): Industrial simulation of fluid flow and fluid-structure interaction with SPH from the VPS software
• Gareth Lee (Altair): Numerical Simulation as a Tool for EV Development: Multiphase SPH for Powertrain Applications
