The goal of project P6 on planetary system dynamics is the dynamical modeling of multiple planetary systems that will be discovered in the course of the CARMENES Survey. Gravitationally interacting planets in a system can tell as much more about their formation and evolution than planets in single systems where those interactions cannot be observed. On top of that the assumption of dynamical stability can even sometimes constrain inclinations and thus individual planet masses in multiple planetary systems.We will carry out dynamical simulations using the SyMBA package in conjunction with a grid search covering a large parameter space in order to assess dynamical stability, the presence of resonances and mutual inclinations among the CARMENES multiple planetary systems. Furthermore, we will also derive ensemble quantities which are tightly linked to the formation and evolution of planetary systems such as the distribution of mutual inclinations or eccentricities. Finally, the analysis of dynamical simulations of multiple or single planetary systems into which potential planets in the habitable zone have been injected can tell us which fraction of systems could in principle harbor planets in the habitable zone, even if those planets do not show up inthe CARMENES data directly. Dynamical simulations will thus help to make full use of the information hidden in the CARMENES data.
