About the Workshop

The main objective of the 1st Automotive CFD Prediction Workshop is to assess the predictive capability of CFD codes for road-cars geometries. Through mandatory geometry, boundary conditions and computational grids the aim is to provide practical modelling guidelines to the automotive community e.g best-practice turbulence modelling, meshing, numerical schemes. In addition we want to bring the automotive CFD community (both academia and industry) together to discuss future directions. In this first year we will focus on external aerodynamics but future workshops will include cooling, aeroacoustics, multi-phase and other elements.

This first workshop will be held on the 11-12th December 2019 in Oxford at St Anne's College. Computing the test-cases is not required to attend the workshop but we strongly encourage everyone to consider submitting results. Three test-cases will be studied; SAE Notchback geometry, DrivAer Fastback and DrivAer Estate vehicle which are described fully in the test-cases section. Meshes have been created for all cases in major grid formats i.e OpenFOAM, STAR-CCM+, Fluent, CGNS in addition to geometry and surface meshes.

Participants who submit results will be automatically allocated a 15 minute presentation slot however those who wish to present relevant material (i.e wind-tunnel campaign of the DrivAer model) without computing the test-cases should send a single-page 500 word abstract to neil.ashton@eng.ox.ac.uk by September 30th 2019 (extended).

There will be a workshop fee of £250 (£200 for PhD students) for the two-day event including tea/coffee breaks and a three course meal on the 11th in the Randolph hotel. Accommodation is available at St Anne's for £82 per night (including breakfast) and due to space limitations there is a maximum limit of 100 people to attend the workshop. You can register for the workshop and accommodation here.

If you wish to submit results please complete the intention to participate form below and you will assigned a unique number.

For those submitting results we require final results to be submitted no later than **November 25th 2019** to allow time to draw some common conclusions and cross-plotting. Please see the test-cases section for data submission details.

Who Should Attend?

Automotive OEMs, start-ups, software companies, academics in the UK and internationally

When and where?

11-12th December 2019 at St Annes College, University of Oxford, England. Agenda coming soon, but events starts ~11am on 11th and finishes ~4pm on 12th.


Please contact neil.ashton@eng.ox.ac.uk for queries about the test-cases/technical issues, or events@eng.ox.ac.uk for workshop/registration related queries

Intention to Participate

Please click the link below to complete a short form to let us know of your intention to participate. We will then contact you to provide you with a unique submission ID for those wanting to submit results. The deadline to complete this form is September 9th 2019. To register for the workshop please click here

Test Cases

Three test-cases are available for participants to compute and submit to the workshop organisors to crossplot and summarize. Each participant who computes these cases will be given a 15 minute presentation slot to discuss their results. Full descriptions of these cases; SAE Notchback (Case 1 (version 0.6 - UPDATED 07/11/2019)), DrivAer Fastback (Case 2a (version 1.9 - UPDATED 28/10/2019)) and DrivAer Estate (Case 2b (version 1.9 - UPDATED 28/10/2019)) are available in prior links with geometry, surface meshes and volume meshes available to download from here. We have provided meshes in all the major mesh formats i.e OpenFOAM, STAR-CCM+, Fluent, CGNS. We would encourage participants to run the coarse, medium and fine meshes to demonstrate mesh convergence. We expect a mixture of RANS, Hybrid RANS-LES and WMLES results so please be ready to justify your choice of numerical schemes, time-steps etc.

If you do decide to use your own mesh please describe this in detail in your submission and contact us to upload it to the FTP site so that other participants can have the chance to use it. You must use the geometry/surface mesh from the workshop transfer area rather than from the TUM website or any other source to ensure all submissions are based upon the same geometry.

Experimental data for Case 1 is available here which has the data itself and some instructions. Please refer to the main test-case description for up to date information.

Please complete the intention to participate form in order to receive your unique ID. Please then submit results following the details in the case descriptions to each test-case co-ordinator no later than November 25th.

Venue and accommodation

The workshop will be held in the heart of Oxford at St Annes College. The main workshop will be held in the state of the art Ruth Deech building , with an evening meal being hosted in the historic setting of Oxford's Randolph hotel.

Directions to the College

St Annes College is situated in Oxford city centre and is a 15 minute walk from the Oxford's train station where regular trains run to London's Marylebone station or Paddington station, both of which are just a few stops by London Underground to St. Pancras station, where Eurostar train connections are available to France, Belgium and beyond. If you are driving to Oxford, parking in the centre is very constrained and we recommend instead parking at one of the local Park and Ride facilities from which regular buses into the centre of town are available. The easiest airport for access to Oxford is London Heathrow and there is a regular bus service that runs between Heathrow and Oxford (terminal 5 is particularly convenient for this).

We have reserved some ensuite rooms at St Annes College for delegates for the night of Wednesday 11th December, including breakfast on 12th December, at a very reasonable rate. We can help to book rooms on the night of Tuesday 10th December for those who might wish to arrive the day before the conference starts - please contact events@eng.ox.ac.uk . The rooms for the night of the 11th December can be booked together with the conference registration and will be available on a first come first served basis, so please book as soon as possible. Link to registration and room booking is here . The policy for refunds is as follows: Notice period % of refund: More than 28 days before the start date - 100%, 14 to 28 days before the start date - 50%, Less than 14 days before the start date - 0%
