N2 - Within the framework of IEA wind Task 39 different benchmark-tests are performed. Here we are presenting a comparison of a particle-based model, a wave-based model and a PE-model with respect to two different test cases. They are of theoretical nature, addressing the influence of a simple meteorology in the first case and a simple topography in the second case. Some non-intuitive behaviour of the models can be observed that is compared for the different models. We will show in particular, how the source (physics or model) of such a behaviour can be analysed and understood. This is important, as some models can create non-physical behaviour - like caustics - whilst at the same time, not all physical effects are captured by different models.
