Finite Elements in Python - The FENICS Package — •Enrico Stein — Physics Department and Research Center OPTIMAS, Technische Universität Kaiserslautern, Erwin-Schrödinger-Straße 46, 67663 Kaiserslautern, Germany

In this contribution the FENICS package for solving PDEs by the method of finite elements is presented. With this method one can solve a PDE numerically without a discretisation of the differential operators themselves. Instead one introduces on every subdomain an ansatz function yielding in the end a linear system of equations for the coefficients of the ansatz.

In this contribution the finite element method is introduced on formal grounds. With this knowledge at hand a simple example solving the Poisson equation with the FENICS package is presented. Afterwards everyone in the audience has the opportunity to participate actively and program his/her own example code. A working installation of the FENICS package for the last part is recommended.
