FFB

CFD for Ship Resistance  RANSURANS  LESDES  FEM 
The FrontFlow/blue (FFB) is a finite element method solver for incompressible turbulent flows by LES and RANS with secondorder accuracy in terms both of time and space. Standard Smagorinsky model (SSM) and dynamic Smagorinsky model (DSM) are implemented for the SGS model, and SA model is implemented for RANS.
CrankNicolson method and fractional step (FS) method are implemented to solve the momentum equations and the pressure Poisson equation, respectively. FFB runs in massively parallel by the domain decomposition method.

CFD for Ship Resistance  Thin Ship Theory 
Flotilla is a computer workbench that can be used for investigations into some aspects of ship hydrodynamics. Flotilla is not suitable for many classes of hulls. It cannot handle planing hulls or very stubby vessels like tugboats. However, it provides very acceptable predictions for hulls with L/B as low as 5 when the hull has a transom stern.

NFA

CFD for Ship Resistance  CFD for Ship Motions and Maneuvering  LESDES  FVM 
NFA (Numerical Flow Analysis) is a fortran code and solves the NavierStokes equations utilizing a Cartesian grid cutcell formulation with a secondorder accurate, volumeoffluid (VOF) interfacecapturing technique to model the unsteady flow of air and water around moving bodies.
Turbulence is modeled with an implicit subgridscale model that is built into the treatment of the convective terms in the momentum equations. A domain decomposition method is used to distribute portions of the solution domain over a large number of processors.
