King’s College London, London, 8-10th June 2026

About

The 10th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in the Nektar++ spectral/hp element framework and the exciting science and engineering being undertaken with the code.

The three days will include a comprehensive programme of talks and a poster session. The workshop will be run as a hybrid event, meaning that attendees can be either in-person or remote. We do however encourage attendance in-person if possible!

Registration and Schedule

Registration for the workshop is now available at https://cassyni.com/s/nektar-workshop-2026 (Link opens in the new tab)

Location

The workshop will be held in the King’s Building, located on the Strand Campus of King’s College London, with lectures taking place in the Nash Lecture theatre (KIN 205).

Getting to the campus

The KCL campus is located in central London and is served by a number of underground stations:

  • Temple (Circle & District line) is the closest with, a 5 minute walk from campus
  • Covent Garden (Piccadilly line), around 10 minute walk.
  • Charing Cross (Northern line), around 10 minute walk.
  • Embankment (Circle & District, Northern and Bakerloo lines), around 12-13 minute walk.

Getting to the rooms

Access to the King’s campus is via the main reception in the Strand Building, located on the Strand. After entering the reception, you will need to sign in at the reception desk. From the foyer, take the staircase on the left-hand side or the lifts up to the second floor. Turn left into the King’s building, and the lecture hall is on the right as you enter the King’s building. Signs will be posted to help you find the rooms from the reception area.

Cost

The workshop is free to attend. Lunch and refreshments will be provided between the sessions. There will be a workshop dinner on 9th June, but self-payment will be required.
