Virtual Marine Arsenal

The U.S. Naval Academy Hydromechanics Laboratory (NAHL) began operations in 1976.

NAPA (Naval Architectural PAckage) is a ship-oriented design tool for naval architects and offers functions for the modeling of ships and performing design analysis calculations. Main features are, 3D modeling of the entire ship, standard naval architectural calculations, hydrodynamic calculations, report generation and drawing functions, communication with other design systems.

Napa Emergency Computer offers user-friendly tools for decision support. In case of an emergency it is important to get fast and reliable support for handling distress situations and identifying the best recovery actions.

Napa Green Monitoring is a solution for planning, monitoring and follow-up of ship operations and helps its users to realize operational savings through increased awareness, trim and voyage optimization and performance analysis while never compromising safety.

Napa Loading Computer ensures safe and optimal planning of stowage, cargo and ballast for different ship types. The system covers a wide range of calculations related to hydrostatics, intact stability and longitudinal strength.

Nauticus Hull is combination of rule check calculations and finite element analysis for ships.

The Nautilus Stability Master is a program displays the ship in three views, showing all of the ship's compartments and how much each one is filled. The program will automatically recalculate the new weight distribution curve and then find the final sink-trim-heel condition of the vessel. The vessel will be displayed in this trim condition and all hydrostatics, stability, and strength results will be displayed.

Naval Designer is an integrated software dedicated to naval architecture. It offers at the same time a graphic modeler, a studio of virtual reality and specific tools for boat design.

NavCad is for the prediction and analysis of vessel speed and power performance. It also provides for the selection of suitable propulsion system components; engines, gears and propellers. NavCad can be used for the design and analysis of virtually any type of monohull or catamaran; from large displacement vessels to fast planing craft.

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.

NEi Software provides composites analysis solutions that allow product and design engineers to examine the structural, dynamic, and thermal aspects of their designs with detailed graphical visualization of data and results.

The School of Marine Science and Technology has a 37 metre towing tank which is used for model experiments related to the performance of ships and other marine vehicles.

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.
