Austrian Competences in Aeronautics Technology


We are specialized in advanced CFD simulations (Computational Fluid Dynamics). We have years of experience in advanced CFD simulations including development of solvers, with a focus on OpenFOAM(c). Committed to developing no-nonsense results we draw on our range of experience in both scientific and industrial environments to design simulations for complex flows.

Technologies and competences

We simulate condensation, freezing, thawing and evaporation of water (with all thermodynamic effects and heat trasfer) for interior (cabin) and exterior applications. We also handle large-scale wind simulations e.g. for wind turbulence around air fields and UAVs in cities with domain sizes of dozens of cubic kilometers even in complex terrain (e.g. 5x5x3 km incl. buildings, hills, trees, ...).
