CFD is most easily described as a virtual towing tank. With state-of-the-art hardware and software, the flow around the ship is simulated with great accuracy and visualised in detail.
On CFDanalysis.com you can make use of advanced FINE/Marine software, specifically developed for the marine environment and adapted by Van Oossanen, the Netherlands-based renowned company that specialises in hydrodynamic research and optimisation services.
Compared to towing tank tests CFD is just as accurate and often more cost effective, especially in the early design stages. In addition, CFD provides an almost unlimited amount of data flow details. This information can be used to improve the hull form, align appendages or serve as input for propeller design.
