INNOVATION: Specialised CFD for Naval Hydrodynamics

---

Short description

Designing ships and offshore object often requires detailed hydrodynamic information in order to produce a more relevant, competitive and safer design. The unique set of numerical methods contained in the software provides a robust, efficient and accurate framework providing a valuable engineering tool for producing better designs.

Long description

The challenge is the complexity of hydrodynamic problems that need to be solved in order to access these information. Finite Volume based Computational Fluid Dynamics is a class of methods that enables the flow problem to be tackled with minimum simplifications and assumptions. Free-surface flow with floating or submerged objects can readily be modelled with high accuracy using this approach. The Naval Hydro pack software based on foam-extend is a specialised software library for large-scale, two-phase flow with 6DOF motion modelling capabilities. It is specially designed and developed to be able to handle a range of problems in the naval industry such as calm water resistance, self-propulsion, wave loads, green water phenomenon, sloshing, slamming and many other. The unique set of numerical methods contained in the software provides a robust, efficient and accurate framework providing a valuable engineering tool for producing better designs.
