+Solving partial differential equations with Firedrake
+-----------------------------------------------------
+
+We will host a 2.5-day in-person tutorial on Firedrake at the
+`Mathematical Institute, University of Oxford
+<https://www.maths.ox.ac.uk>`__ from 18-20 March 2026. This training event is kindly supported by the `Collaborative Computational Project on Data-centric Computational Mechanics <https://ccp-dcm.github.io/>`__ and the `Computational Science Centre for Research Communities (CoSeC) <https://www.cosec.ac.uk/>`__.
+
+The tutorial is aimed at all levels, from MSc students to senior faculty and those solving partial differential equations in industry. Only a basic passing knowledge of finite elements is necessary, although of course knowing more background is still useful.
+
+The course will cover both the basics of solving stationary and time-dependent problems, as well as various advanced topics like geometric multigrid and 𝑝-multigrid solvers, high-order mesh generation and adaptive mesh refinement with Netgen, nonlinear problems, mixed formulations and block preconditioners, eigenvalue problems, and adjoints.
+
+Attendees will need to bring a laptop. Installing Firedrake (see the
+:doc:`download page <install>` for details) is optional, as it will be
+also be possible to join the tutorial using the cloud. Installing `Paraview <https://www.paraview.org>`__ for visualisation before the course is recommended.
+
+
+Registration
+------------
+
+Registration of £25 covers tea, coffee, and biscuits. Registration will open presently.
+
+
+Where and when
+--------------
+
+The conference will take place in the Andrew Wiles Building. Its main entrance
+is located on Woodstock Road (`see here for the precise location
+<https://what3words.com/policy.rises.bets>`__). Take some care in navigation, as
+Google Maps sometimes directs people to the old mathematics building on St.
+Giles.
+
+The course will begin at 13:00 on March 18 and end at 16:00 on March 20.
+
+Travel to Oxford
+----------------
+
+(This advice is an adaptation of `Mike Giles' advice <https://people.maths.ox.ac.uk/~gilesm/travel.html>`__.)
+
+Coming to Oxford from abroad, the best options are:
+
+* Flying to Heathrow
+
+   This is usually the best option for those flying long distance. There is an excellent `direct bus service to Oxford <https://www.theairlineoxford.co.uk/oxford-to-heathrow-bus/>`__ (when you approach the bus the driver will ask which stop in Oxford you want; tell the driver you want to go to Gloucester Green bus station, "Gloucester" is pronounced "gloster") with 2-3 buses per hour taking 80-90 minutes from the Heathrow Central Bus Station (Terminals 1-3) and Terminal 5. Those flying into Terminal 4 must first change and take local transport at Heathrow to get to Terminal 5.
+
+* Flying to Birmingham
+
+   This is a good option for European flights; Birmingham is a much smaller airport than Heathrow and is more convenient. There is a `regular train service to Oxford from the adjacent Birmingham International station <https://www.crosscountrytrains.co.uk/>`__. There is usually one train per hour, and they take about an hour. The trains can get quite busy, booking in advance is advisable.
+
+Other, less convenient options are:
+
+* Flying to Gatwick: the direct bus service is less frequent and takes up to 2.5 hours.
+* Flying to Luton or Stansted: two more airports near London but neither has convenient public transport links to Oxford.
+* Eurostar train to St Pancras station in London: onward travel to Oxford requires a 30-minute underground train journey to Paddington station, then an hour's train journey to Oxford.
