The course is a continuation of FMNN10 Numerical methods for differential equations and the purpose of the course is to deepen the doctoral student's knowledge of partial differential equations, with an emphasis on numerical approximation of solutions, and to provide practical training in solving relevant computational problems in a python environment with tools in DUNE (Distributed and Unified Numerics Environment), a modular numerical toolbox for partial differential equations.

Theory for ellipic partial differential equations (PDEs): Well-posed problems. Weak theory of solvability. Existence and uniqueness. Stability with respect to data, and approximation of solutions. Regularity of solutions.

Solution with the Finite Element Method in DUNE-FEM: Introduction to DUNE-FEM. Discretization of boundary value problems for PDEs in DUNE-FEM using the Finite Element Method. Construction of finite elements, e.g. discretization grids, reference elements, degree of freedom (DOF) mappings.

Using the Unified Form Language (UFL) in DUNE-FEM for description of weak forms of PDEs,

Parallelization of Finite Element methods using domain decomposition,

Adaptive Finite Elements.
