The first step is to download and install Firedrake and its dependencies. For full instructions, see obtaining Firedrake.
Once you’ve built Firedrake, you’ll want to actually solve some PDEs. Below are a few tutorial examples to get you started.
- A basic Helmholtz equation.
- The Burgers equation, a non-linear, unsteady example.
- A mixed formulation of the Poisson equation.
- A time-dependent DG advection equation using upwinding.
- An extruded mesh example, using a steady-state continuity equation.
- A linear wave equation with optional mass lumping.
- Creating Firedrake-compatible meshes in Gmsh.
Firedrake has a youtube channel where recorded tutorials are occasionally uploaded.
The complete list of all the classes and methods in Firedrake is available at the firedrake package page. The same information is indexed in alphabetical order. Another very effective mechanism is the site search engine.
Once you have worked through the tutorials, the user manual is the next step. It goes in to more detail on how to set up and solve finite element problems in Firedrake.
