Several DUNE modules provide tutorials:

• dune-fufem: UFL-style assembly of variational PDE problems in both C++ and Python

• dune-functions: Direct access to many different finite element space bases

There are also several dedicated tutorial modules:

• dune-fempy: A tutorial on using the DUNE-FEM discretization module through Python

• dune-pdelab-tutorials: Tutorial for PDELab providing a range of C++ examples
