Abstract
It is often sufficient to study fluids On the other hand, there are certain phenomena or situations where the stresses on or by a fluid or a solid can lead to large deformations, and the interaction between fluids and solids are essential Computational fluid-structure interaction (FSI) is an active field of research with much focus on numerical accuracy, stability, and convergence rates. At the same time, there is also a sweet spot in between these areas of research where there is a need to experiment with FSI without having an in-depth, bottom-up mathematical understanding of the problem, but where a physical insight might suffice. Therefore, the aim was to develop a fully monolithic and robust entrylevel research code with ease-of-use targeted towards students, educators, and researchers.
