Computational Fluid Dynamics (CFD) – Special Interest Group rebooted

Published: Posted on

Computational Fluid Dynamics (CFD) is used in a variety of engineering disciplines, including civil, railway, river, coastal, tidal, meteorological, and chemical engineering. There are a variety of CFD packages commercially available including ANSYS CFX, ANSYS FLUENT and the open source software OpenFoam.

Bruno Fraga, the chair of the CFD Special Interest Group is inviting you to be part of this group. Bruno has organised the CFD seminar series with experts from academia and industry.

CFD Seminar Series – Spring 2023

Seminar 1 – Water Modelling in Engineering Practice
Presenter: Dr. Luis Priegue – Welsh Water/Dwr Cymru
Location: LG15, Learning Centre
Date: 24/03/2023
Time: 11 am-12:30 pm

Dr. Priegue will give a two-part seminar/workshop. In the first half, he will discuss water quality modelling in the context of wastewater treatment. This part will include some insights into how a water utility company such as Welsh Water deals with this topic and examples of real-life projects. The second half of the seminar will include an introduction to some of the common modelling approaches for river hydrodynamics and a hands-on tutorial of a 2D shallow waters model called Iber. Attendants will be provided with materials for this second part.

Seminar 2 – Engineer What’s Ahead
Presenter: Michael Doherty – ANSYS
Location: School of Engineering, Room 127
Date: 28/03/2023
Time: 10-11 am

Mr. Doherty will provide us with an overview of CFD applications to the industry. He will showcase the array of potential modelling solutions within the ANSYS software portfolio, with particular emphasis on the newest additions. The School of Engineering possesses ANSYS software licenses that students and PGRs can utilise.

Seminar 3 – Flow3D HYDRO: introduction and workshop
Presenter: Mark Keating – Flow Science
Location: Learning Centre, Room UG08
Date: 28/04/2023
Time: 9.30 am-12 pm

Flow3D HYDRO ( is a very interesting tool to simulate hydraulic structures and free-surface flows, among many other things. In this seminar, Mark Keating will first introduce us to the solver and lead a hands-on session later in which the attendants will be able to access the software and try it with different tutorial cases under his guidance. Flow Science has provided a pool of licenses for students and PGRs to use.

Seminar 4 – Multiflow3D: an introduction to an in-house CFD solver
Presenter: Dr. Bruño Fraga – UoB
Location: School of Engineering, Room 127
Date: 09/06/2023
Time: 10 am- 12 pm

Multiflow3D is a fluid dynamics solver developed within the School of Engineering by Dr. Fraga and his group. This is a highly parallelised solver that is primarily designed to simulate turbulent multiphase flows, with a particular emphasis in particle-laden flows (bubbly flows in water, sediment transport in rivers, aerosols and droplets in air, dust, etc.). The new release of this software will be presented together with some materials and a hands-on tutorial session. It is recommended to bring your own laptop.

Slack Group

We have created a Slack group for those users and developers of CFD. Dedicated channels ensure agile messaging and feedback within a variety of topics, and an opportunity to share news and content. If you or your students are interested in joining, please use this link:
