Virtual Marine Arsenal

Aqua+ is a diffraction/radiation potential flow solver for seakeeping computations of forces and motions induced by waves on single or multi-bodies.

Ansys Aqwa is a three-dimensional linear diffraction/radiation panel code for simulation and analysis of single or multi-body marine structures in six degrees of freedom. It includes Morison elements that can be used to analyze and simulate complex mooring systems and riser systems.

BOAT3D estimates the forces on a hard-chine planing boat using an added-mass analytical approach and solves for the predicted trajectory of motion of the boat in waves. For a given specification the program estimates the forward boat speed, trim angle, height of CG relative to sea level, and horizontal pressure and skin friction resistance forces, as well as horizontal and vertical accelerations and first and second time derivatives of trim.

CFDShip-Iowa solves the incompressible Reynolds-averaged Navier-Stokes and continuity equations with a variety of turbulence models, and a single-phase level set method to accommodate free surface problems. Since it has been specifically developed for surface-ship and marine-propulsor flow problems, it has an array of ship hydrodynamic specific subroutines and post-processors.

Fredyn simulates the dynamic behaviour of a steered ship subjected to waves and wind. All six degrees of freedom are computed in the time domain, where the motions can be large up to the point of capsize.

FreSCo+ is a Free Surface RANS code for maritime applications such as; wave resistance predictions, ship wake predictions, ship dynamic behavior in waves, maneuvering predictions, and propeller flows incl. cavitation.

Icare is a 6 degrees of freedom free surface Navier-Stokes solver, dedicated to the calculation of ship resistance and powering, ship added resistance in waves, seakeeping and maneuverability.

Integrated Hydrodynamics Design Environment (IHDE) is a tool which developed by NSWCCD to execute analyses of alternatives for dozens of ship concept options quickly with reasonable accuracy by combined resistance and seakeeping predictions. IHDE is available for use on US Government projects only.

Maxsurf Motions module for hydrodynamic and seakeeping analysis provides calculation of vessel response and seakeeping characteristics in a variety of sea states for many types of designs created with Maxsurf Modeler.

NavyFOAM is an OpenFOAM derivative specially tailored and customized for broad range of hydrodynamic studies by  NSWCCD for use on US Government projects and the code is not being redistributed. It possibly contains some new schemes and models mainly for VOF. The hydrodynamic interests are powering, propulsion, propulsor inflow, maneuvering and seakeeping computations.

NewDrift is a code for the seakeeping and wave induced loads analysis of ships and arbitrarily shaped floating structures, including multi-body arrangements.

The code enables the evaluation of 6DoF first and quasi second-order motions and wave-induced loads, including drift deviations, forces and moments and is applicable to arbitrarily shaped 3D floating or submerged bodies, operating at zero or nonzero forward speed, finite or infinite water depth and being excited by sinusoidal linear waves of arbitrary frequency and heading.

NFA (Numerical Flow Analysis) is a fortran code and solves the Navier-Stokes equations utilizing a Cartesian grid cut-cell formulation with a second-order accurate, volume-of-fluid (VOF) interface-capturing technique to model the unsteady flow of air and water around moving bodies.

Turbulence is modeled with an implicit subgrid-scale 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.

Octopus-Office is a hydrodynamic analysis program for the calculation of seakeeping characteristics of ships and other floating structures, with or without forward speed.
