Tropical cyclones

Aims

The dynamic behavior of the atmosphere is driven by processes on a wide range of spatial and temporal scales. In this project, those parts of model systems which describe the fluid dynamics and the temperature evolution were investigated. The models are formulated in terms of the velocity, temperature, pressure, and density. We employ a hierarchy of different physical models with an increasing degree of complexity.

Why using HiFlow3?

The flexibility of HiFlow3 allows us to choose appropriate finite element discretizations (Q2/Q1) as well as to implement efficient and effective stabilization schemes (SUPG/PSPG) with respect to the considered model. Furthermore, the scalability and efficiency of the linear algebra and solver modules facilitate the implementation of highly scalable and efficient model-adapted solvers/preconditioners.
