Welcome to the most comprehensive CFD Workshop ever! This unique workshop will guide you through resistance prediction at multiple scales, from model tests to full-scale, propeller performance evaluation and self-propulsion test. 

Designed for engineers, researchers and students in maritime and fluid dynamics, the workshop combines hands-on CFD training with real-world applications, giving you the opportunity to analyze, simulate and validate ship performance like never before.

To make the experience accessible to everyone, there will be three levels of participation: basic A and basic B (Package 1), intermediate (Package 2) and advanced (Package 3); each tailored to your experience and learning goals.

Join us to experience cutting-edge simulations, practical insights and expert guidance in one of the most advanced CFD events worldwide.

Q1: Will the experimental dataset and the geometries be made available to the public after the workshop?

A1:  This will be discussed at the final meeting in October.

Q2: For the Lucy Ashton Workshop most of the effort and thus resources actually went into the post-processing to extract all the required data. Could you give an overview what exactly is the data to be submitted for each package, so the effort can be estimated. Could you please also include if there are any modifications of the data required such as a change of coordinate system.

A2: The answers to these questions are provided in the PDF document titled “CFD Workshop 2026 – Preliminary Document”.

Q3: Could you clarify, how the workshop is held? Online or via recorded video? Also, which tools or software have you used for training? If we don’t have the license of them, what would be the next step?

A3: It is important to distinguish clearly between these two: The workshop is a research- and case-oriented activity. Participants perform their own simulations, submit results, and take part in technical discussions and benchmarking. The emphasis is on analysis, validation, and scientific contribution. Trainings, on the other hand, are hands-on, software-specific courses. These will be organized after the completion of the workshop and will focus on: step-by-step case setup, meshing strategies, solver settings, post-processing workflows, for specific CFD tools. 

Not having a license does not prevent participation in the workshop. Since no specific software is mandatory, participants can use alternative commercial solvers they already have access to or use open-source CFD tools.

If participants are interested in learning a specific tool, this will be addressed later through the dedicated training sessions, where licensing options and access will be discussed separately.

Q4: I understand that the Advance Package should submit results by the 31.05.2026 whereas all other Package are to submit results by 15.08.2026 – that can’t be true, right, since the Advance Package has the most simulations?

A4: The Intermediate package and the Advanced package are connected; therefore, the results from the Intermediate package (not the Basic package) must be submitted no later than 31 May 2026. After that, you will have a period of 2.5 months to complete the six simulations from the Advanced package, as well as any remaining simulations from the Basic package if they have not all been completed.

Q5: I’ll have to check internally whether we are happy paying the fee without knowing on before hand the quality of the input files.

My personal mileage led me to conclusions that what is considered to be good for a given workflow, can easily break in someone else’s one. At least, that is my experience from the Jores2 data, if you participate for this one.

(I do not care about the prize money. If we decide to participate, it is to have a comparison with others, not to be paid to do so.) I wanted to download the video recording, but it seems like I have to request access?

A5: Mail with a WeTransfer download link was sent.  As for your concern regarding the quality of the 3D models, I personally performed CFD analyses for all packages, from Basic to Advanced, and everything was carried out without any issues. Otherwise, I would not have organized the workshop without prior verification, as that would be highly unprofessional on the part of the organizer. If any issues arise, our team will be available to resolve them in the shortest possible time.  We approached the organization of this workshop seriously and with full dedication, fully aware of certain shortcomings that have occurred in previous workshops of this type. Our goal is to raise the standards for how such workshops are set up and conducted and to remain available and supportive to all participants at all times. Of course, there is always the possibility of making mistakes, but that is precisely why engineers exist, to identify and resolve problems efficiently. 

Q6: Is attendance at the final discussion session (online or offline) mandatory for participation to be considered complete, or for certificates and evaluation to be issued?

A6: Attendance at the final discussion session (whether online or in person) is completely optional. This session is primarily intended for discussion of results, networking, and if participants wish, the opportunity to present their own work related to the topics covered by the workshop. Participation is considered complete regardless of attendance at this session, and certificates will be issued in electronic form to all participants.

Q7: Although the workshop is structured as a blind CFD challenge, will participants have the opportunity during the workshop to review solver setups and results with the organizers, in order to identify potential mistakes and improve methodology?

A7: Yes. Although the workshop is structured as a blind CFD challenge, a review of solver setups and results will be possible after the workshop is completed. At that stage, all participants will receive personalized feedback from the organizers, aimed at identifying potential mistakes, discussing modeling choices, and improving overall CFD methodology.

Q8: Regarding potential co-authorship of journal papers or books, will this opportunity be open to all participants, or subject to further selection? If selection applies, could you please clarify the main criteria? Additionally, does participation in more advanced packages influence eligibility for co-authorship?

A8:  Potential co-authorship is open to all participants who are interested in active involvement in writing.
 ach package (Basic, Intermediate, Advanced) will result in a separate article, with possible further subdivision depending on the quality and characteristics of participants’ results. In addition, there is a possibility for independent joint publications between a participant and the organizers, provided that the participant takes the initiative to significantly extend the research beyond the scope of the workshop. Participation in more advanced packages may naturally provide broader material for publication, but co-authorship is primarily determined by the level of contribution and engagement, not by package level alone.

Q9: Why do you impose choosing no-slip condition on all the walls since it might not be what the participants are used to (since it is much more demanding in terms of computational time and resources)?

A9: This can be taken into account, and in the final case description document the choice of conditions will be left to the participants, allowing them to define them according to their own best practices.

Q10: Is this workshop online or onsite?

A11: Please see answer A3.
