Newcastle University, Newcastle Upon Tyne, UK, 11-13th June 2024

About

The 8th 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 attendees can be in-person or remote. We do, however, encourage attendance in person if possible!
