Event description
This workshop provides an introduction of OpenFOAM and how to use it, as well as a platform for networking and discussion.

About this Event

SUMMARY OF THE EVENT

OpenFOAM is a world-leading open-source simulation toolbox. It is used across a wide range of disciplines including engineering, physics, chemistry and biology. By employing OpenFOAM, we can simulate and analyse fluid flows, solid mechanics and fluid-structural interaction. Advanced post-processing techniques can be employed to visualise results and gain a deep insight into complex physical problems.

The 3rd UCL OpenFOAM Workshop is going to be held from the 24th to the 26th of February, 2021. It aims to help beginners to start using OpenFOAM for their projects, as well as to create a platform for experienced users to collaborate. It is totally free and initiated as a UCL Doctoral Skills Development Programme. The workshop will provide two types of sessions: (a) cutting-edge research in this area, which focuses to promote knowledge exchange (b) hands-on tutorials, which helps new users to quickly understand and use OpenFOAM.

In 2019, the 2nd UCL OpenFOAM Workshop was held at UCL during 26-28 June, with a total attendance of 55 experts and students. It was a very successful on-site event; we received great feedback from the participants, but also, strong interests from worldwide users who wanted to attend but could not join us in London.

As a consequence of the COVID-19 pandemic, the 3rd generation of this event will be held fully online, which in turn allows us to invite more speakers and reach a wider audience. There is no threshold for registration – anyone from any institution can register via Eventbrite without a fee. There is no limit regarding the amount of participants during the event.

This event is a great chance to improve your simulation skills and discuss solutions for your projects. This project has exclusively won the Research-led Initiative Award of UCL, three times, in 2018, 2019 and 2020.

Each of the workshop day is planned to start with keynote speeches during the morning sessions, followed by hands-on tutorials/trainings in the afternoon. Subjected to the presenters’ willing, some of the presentations will be recorded and published online, for the purpose of future studies.

You will have the chance to get some hands-on experience of using OpenFOAM to analyse a number of fluid problems and will learn first-hand how OpenFOAM works and what it can do. This will include step-by-step tutorials to teach applications of OpenFOAM in maritime and civil engineering. You will learn how to model multiphase flows for ship hydrodynamics, ocean waves as well as a number of fluid-structure interaction problems involving vibrations and deformation. Furtherly, you will learn how to programme in OpenFOAM to implement extended mathematics and physical models, which means you are able to add something new and be able to tailor solvers, boundary conditions and post-processing functions to your specific needs.

** It is important to have OpenFOAM installed before the workshop in order to maximise your participation and input during the tutorials. The installation guidelines with a suggested version are available after you sign up (for download), please try to install at least one week before; and if you have problems, do not hesitate to contact us. **

*** There will be an awarding session aspiring to acknowledgement those who have made substantial contributions to the OpenFOAM community, especially considering those who constantly make contributions despite the tough time brought by COVID-19.

There will be around three awardees, to be announced during the session. They will be given a certificate and a generous gift, which will be funded by UCL.

Before 10/02/2021, anyone can submit nominations to the local organising team alongside reasons (via the email address below). Nominations will be passed on and selected by the International OpenFOAM Workshop Committee.***
