Nektar++

June 10th – 12th, 2019, University of Exeter, Exeter, UK.

Objective

The 4th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in Nektar++ and the exciting science and engineering being undertaken with the code. This year, we will host the workshop at the University of Exeter.

The first two days will include a comprehensive programme of talks, which will be followed by a number of parallel informal group sessions allowing developers and users to discuss and work on specific aspects of the code.

Schedule

Talks are generally 15 minute presentations + 5 minute Q&A.

Location

The workshop will be held in Streatham Court on the Streatham Campus of the University of Exeter, just outside Exeter City Centre.

Getting to campus

Directions to campus are available from the University of Exeter website. The main rail station at Exeter is Exeter St. David’s, for which there are direct services from London Paddington (around 2.5hrs) and London Waterloo (around 3.5hrs).

Getting to Streatham Court

The workshop talks will take place in Lecture Hall B of Streatham Court. Streatham Court is located at the bottom of central campus. It is building 31 on the campus map. Streatham Court is about a 20 minute walk from Exeter St. David’s train station.

Getting to The Forum

The workshop breakout sessions will take place in the Exploration Labs in the Forum Building. The Forum is located at the heart of central campus and is building 3 on the campus map. The Forum is around a 20 minute walk from Exeter St. David’s train station.

Accommodation

The University of Exeter is just outside the city centre and can be reached via a short walk of around 20-30 minutes, depending on location. The closest physical hotel is the Premiere Inn, located next to St. David’s. Other hotels include the Mercure Exeter Rougemont Hotel, the Clock Tower Hotel and the Hotel du Vin. There are also several Bed & Breakfast venues at lower costs close to the University.

Cost

The workshop is free, but accommodation and the dinner is not covered and expected to be paid by the person attending.
