Call for Abstracts (closed)

Whether you are an SU2 user or developer, student or professional or enthusiast, everybody is welcome to participate in our upcoming 6th Annual SU2 Conference and share their work with our community. Aside from state-of-the-art research, we also highly encourage you to share code contributions, work-in-progress or other work related to SU2.

Topics include but are not limited to: Computational Fluid Dynamics (CFD), Turbomachinery, Multiphysics (e.g. CHT, FSI), Shape/Topology Optimization, Adjoint Methods, Algorithmic Differentiation , Surrogate Modelling, Visualization Techniques, etc.

In-Person presentation in Varenna is not always possible, so we will give you the opportunity to present virtually (but live) as well.

The authors will need to register their email with CMT. Here is a link how to create a CMT account:
https://cmt3.research.microsoft.com/docs/help/general/account-creation.html.

Abstract Submission Guidelines

• Please prepare a ~250-1000 word abstract about the work you want to present, preferably just as a text that can be added within cmt and upload a .pdf-file.
• The abstract has to be submitted via CMT
• The extended deadline for submitting an abstract is August 31st 2025.
• Acceptance notifications will be sent out latest Friday, August 31st. The organizing committee, as listed below, reviews the submissions and decides about acceptance or rejection.

Registration (Early bird)

Please note that this year a differentiation is made between the registration for the conference (29th-30th Sept.) and the registration for the Turbo Workshop (1st-2nd Oct.). See the two following paragraphs below for more info.

SU2 Conference

The registration is now open for in-person and virtual participants via a third party platform. Virtual participation is free of charge while the in-person fees are 500€ for (PhD-)students and developer to the code, the fee is 1000€ for everyone else (professional). The fee pays for the conference venue and catering spanning the 2 conference days, but not for accommodation.

Note: There is limited accommodation on-site (i.e. in the conference venue) available that is managed through the SU2-Foundation and we are very happy to accommodate you, but please get in touch with the Foundation for that first so that we won’t be overbooked. Thanks already.

Please click the button below to go to the registration platform for virtual tickets please also for in-Person tickets. Especially if you are not sure which category you fall in, then we figure that out with you.

Alternatively you can directly go the payment website, register there and choose the appropriate options for the 3 categories: conference fee type, conference accommodation type, turbo workshop fee type. Please consider the above comment regarding limited on-site accommodation.

Turbo Workshop

There are 3 ticket types for the Turbo workshop this year:

1. You attend in-person, but you do not attend the conference before: 350€
2. You attend in-person, and you do attend the conference before: 150€
3. You attend virtually: 150€

There are no student/contributor discounts. No on-site accommodation is possible during the Turbo Workshop.

Please use the registration platform and payment platform given for the conference above, they are set up to accommodate both, conference and Turbo Workshop.
