founder

Andreas has more than 20 years of experience in hydrodynamics, CFD modeling and maritime engineering.

Over the years, he has been involved in numerous research and industry projects covering general fluid flow, propulsion performance, and load analysis of ships and offshore structures.

Today, his work focuses on physically consistent CFD analysis with Siemens STAR-CCM+® and consulting services in hydrodynamics and flow engineering, including methodological reviews and technical advisory work.
