Description

The FEniCS 2026 conference is an opportunity for all those interested in the FEniCS Project and related projects to exchange ideas, communicate their results and network with the automated scientific computing community. It will be hosted in Paris (France) at University of Chicago | John W. Boyer Center.

We welcome developers, existing and potential users of the FEniCS ecosystem, as well as mathematicians, computer scientists, and application domain specialists interested in numerical methods, their implementation and applications.

The FEniCS 2026 conference emphasizes an open and inclusive atmosphere, contributed talks from a diverse range of scientific areas, and dedicated time for discussions and coding.

Links to previous FEniCS conferences can be found here.

Important dates

• Registration to the conference is closed: 2 June 2026.

Conference programme

The conference programme can be found here. Minor adjustments are still possible so please check the programme again just prior to the event.

Book of abstracts

The preliminary book of abstracts is available on Zenodo. Participants are encouraged to review their abstracts and submit a PR if changes are needed.

Practical information for participants

• Presentation session: due to the high volume of submissions, we have adopted a shorter 10-minute presentation format. The full 15-minute slot includes time for questions and speaker changeover. Please be mindful of the other participants and keep your presentation concise so that everyone has equal time to present. We will be using a timer visible to the audience and the speaker to keep track of the sessions.
• Poster session: please bring your poster in A1 or A2 portrait format. Mounting material will be provided on site. Thanks to Flax & Teal for sponsoring the poster session.
• Software session: please bring your own laptop to demonstrate your FEniCS-based software to small groups. These “software demonstrations” take place at the same time as the poster session.
• Poster & Software sessions: blitz! Since last year, we have included a short overview session of all posters, the Poster Blitz. This year, it will also include software demonstrations for participants who are not giving a talk. Each participant presenting a poster or software demonstration will have a maximum of 1 minute to introduce their work at the end of the second session on the first day (17:15–17:30). The full list of participants who must prepare a one-minute blitz presentation can be found in the conference programme (after session 2).
• The registration fee includes: conference activities, coffee breaks, conference dinner, and social events. The registration fee does not include lunches, and it is non-refundable.
• All participants are welcome to attend an optional Advanced Tutorial Session in the morning on Wednesday, 17 June. More details are available in the conference programme.

Conference venue

The conference will take place at:
University of Chicago | John W. Boyer Center
41 rue des Grands Moulins
75013 Paris
France

Getting there

The University of Chicago | John W. Boyer Center is situated in the 13th district of Paris, which makes the venue easily accessible via public transport (metro, tram, RER, and bus).

For your convenience, we recommend installing the official Île-de-France Mobilités application on your smartphone. It allows you to buy tickets, plan your journey, and check real-time traffic information.

If you are arriving by air:

• From Paris-Orly Airport (ORY): Metro line 14 is the fastest public-transport connection to Paris, and it serves the airport directly.
• From Paris-Charles de Gaulle Airport (CDG): the RER B is the main rail link to Paris and serves major hubs such as Gare du Nord and Châtelet.

Note: to reach the city from both airports, you need to buy a special ticket (€14 one way).

If you are arriving by train:

• Gare d’Austerlitz is especially convenient, as it is located in the 13th arrondissement and is connected to metro lines 5 and 10 as well as RER C.
• Gare de Lyon is also a practical arrival point, with connections to metro lines 1 and 14 and RER A and D.
• Other major Paris stations, including Gare du Nord, Gare de l’Est, and Gare Montparnasse, are well connected to the city’s transport network; the Île-de-France Mobilités app is the easiest way to plan your onward journey to the venue.

Accommodation

Accommodation is not included in the FEniCS conference registration fee; participants are responsible for making their own arrangements.

The conference host, the University of Chicago | John W. Boyer Center, has provided a list of hotels offering special booking rates, which can be found here. When making your reservation at any of these establishments, please request the University of Chicago Paris Center rate.

Lunch and Coffee Breaks

Coffee breaks are included in the conference registration fee; participants are responsible for their own lunch. For your convenience, a list of restaurants located within walking distance of the University of Chicago | John W. Boyer Center can be found here.

Travel awards

Flax & Teal and d’Alembert Institute | Sorbonne University have kindly offered to support travel awards for attendees who would otherwise struggle to come to the conference for financial reasons. Priority will be given to junior students and researchers or those working in countries with a less developed research infrastructure. Applicants are strongly encouraged to submit an abstract to the conference.

• Applications to travel awards were closed on 27 March 2026.

Code of conduct

We expect all attendees of FEniCS 2026 to follow the FEniCS Project code of conduct. Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the conference organizers or the FEniCS Steering Council.

Grading system for presentations

Judges use a seven-point scale (0-7) to judge presentations on the following criterion.

The score for each statement is weighted equally into a final score. The final decision is made jointly in the judges deliberation session taking the score and other comments into account.

Comprehension & Content

• The speaker provided clear background and significance to the research question.
• The speaker clearly described the research strategy/design and the results/findings of the research.
• The speaker clearly described the conclusions, outcomes and impact of the research, and was able to answer audience questions.

Engagement & Communication

• The oration was delivered clearly, and the language was appropriate for a non-specialist audience.
• The presentation slide deck was well-organized and enhanced the presentation.
• The presenter conveyed enthusiasm for their research, articulated thoughtful answers to questions, and captured and maintained the audience’s attention.

Grading system for posters

Judges use a seven-point scale (0-7) to judge the the poster and its presentation during the session on the following criterion:

Comprehension & Content

• The poster provided clear background and significance to the research question.
• The poster clearly described the research strategy/design and the results/findings of the research.
• The poster clearly described the conclusions, outcomes and impact of the research, and the presenter was able to answer the questions of the judges.

Engagement & Communication

• The poster used language was appropriate for a non-specialist audience.
• The poster was well-organized and visually appealing.

Nate Sime Award for Exceptional FEniCS Visualization

This award is intended to acknowledge the effort scientists place into the visual presentation of their work.

The winning image or video is judged to be most beautiful according to the committee’s subjective sense of aesthetics. Emphasis is given to the visual appeal of the image or video rather than the impact of the underlying science. Ideally the winning image or video summarises the complexity of the underlying science for the uninitiated scientist (“a picture tells a thousand words”).

The image or video must be:

• Composed from data generated primarily by using the FEniCS Project.
• Relevant to the advancement of science.

Sponsors

We acknowledge the generous support from the Flax & Teal to sponsor travel awards and poster session

as well as d’Alembert Institute | Sorbonne University for sponsoring the travel awards

We further thank sponsorship from the Ridgway Scott Foundation to support Best Presentation and Poster Awards.
