# Workplan/Roadmap
## Project Description
The goal of the thesis is to enable simulations of gas flows (e.g. rarefied or diluted gases) in non-equilibrium. The open-source computing platform FEniCS [1] is used to solve the corresponding partial differential equations using the Finite Element Method. The full regularized 13-moment (R13) equations are first linearized and two decoupled systems of equations are considered. Numerical solutions of these systems have to be studied compared to analytical solutions that can be found in existing work in this research field [3].
Part of this work is also a step towards the numerical analysis of more complex model equations and problems describing flows in microscopic settings, i.e.:
- generation and validation of new test problems
- inclusion of the coupling terms to solve the full linear system
- implementation of the above-listed models in the three-dimensional setting
- extension of the steady models to the transient case
