Boat3D is a software which does
3-degree-of-freedom simulation of planing boat motion, predicting
(at planing speeds) boat performance in calm water and waves from
hydrodynamic theory. For a given boat design, 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. Boat3D lets you estimate the speed you will obtain from
a particular design for a given engine/propeller thrust. It also
lets you estimate the accelerations imposed on the boat occupants
at a particular speed in a particular sea condition, and the amplitude
of the pitching response to the sea.
||LAMP is the SAIC three-dimensional
time-domain Large Amplitude Motions Program. It calculates time-domain
motions and loads of floating bodies with or without forward speed,
and it can be used for the numerical solution of many seakeeping-related
problems. Its prediction capabilities include the following: impulse
response functions wave resistance of ships in calm water or in
waves linear and nonlinear motions of vessels in waves linear and
nonlinear hydrodynamic forces linear and nonlinear wave excitation
forces pressure distribution over the hull surface linear and nonlinear
wave loads impact and whipping loads nonlinear simulation of time-domain
ship motions in large-amplitude waves.
||Predicts the heave,
pitch and surge response of a planing hull as it encounters regular
or irregular seas. When the forward velocity or thrust and the shape
of the waves or wave spectrum was specified, the hulls motion
including surge, heave and pitch displacements, velocities and accelerations
will be calculated. It will help you to predict time dependent effects
such as porpoising, deck wetting and boat accelerations.
||A hydrodynamic and
seakeeping analysis program that provides fast, reliable calculation
for many types of designs in a variety of sea states. Can directly
works with maxsurf surface models.
motion of a numerical hull model in wind-sea and swell. It animates
three-dimensional interactions between the ship and the waves with
the graphics card in your personal computer. It shows changes in
trim and motion that result from changing load or hull shape. SeaShip
needs two inputs, a numerical model of the hull, and a sea and swell
||Seaway is a frequency-domain
ship motions program, based on the linear strip theory to calculate
the wave- induced loads, motions, added resistance and internal
loads for six degrees of freedom of displacement ships and yachts,
barges, semi-submersibles or catamarans, sailing in regular and
irregular waves. This 2-D potential theory program is suitable for
deep water as well as for shallow water. Viscous roll damping, bilge
keels, anti-roll tanks, free surface effects and linear springs
can be added.
||ShipmoPC is a strip
theory-based, frequency domain seakeeping code capable of computing
the six degree-of-freedom motions of a monohull with forward speeds
in regular as well as irregular seas of arbitrary headings.
||Shipmo-Marin is based
on the well-known 'strip-theory'. The potential theory underlying
Shipmo hinges on the slenderness of the ship's hull and on linearity
of the hydrodynamic forces. The program is actually split up into
two parts. In the first part the hydrodynamic reaction forces, expressed
in added mass, damping and wave forces, are calculated. In the second
part of the program the sectional coefficients are integrated over
the ship length and the equations of motion are solved. The integration
can also be carried out for a segment of the ship, which gives the
possibility to calculate the internal loads in the hull, like bending
moments, shear forces and torsional moment.
||The Ship Motions Program
is a program for predicting regular wave responses and statistical
information from an initial hull geometry. The motion can be calculated
with five degrees of freedom; heave, sway, roll, yaw and pitch.
Different types of spectra may be used to generate the statistics,
and wave spreading may be invoked. The wave angles may be from any
direction between ahead and astern.
||Skip is a code for
the prediction of the seakeeping behaviour for the monohull configuration.
The code is based on strip theory assumption and is able to calculate
the linear transfer functions of the rigid-body motions in 6 DOF
in waves. The hull geometry described by Lewis forms and the vertical
motions are evaluated in terms of vertical and lateral shear force,
vertical and lateral bending moment and torsional moment. There
is also a twin hull configuration version; Twinmot.
||Soap is a code to
perform seakeeping operability analysis in the short- and long-term
according to the newest criteria related to human factors. The code
has an interfacing facility with a generic linear seakeeping code
in the frequency domain via a standard format file.
||SPLASH is a fully
3-D nonlinear free-surface potential flow panel code for aero/hydrodynamic
design and anlysis of marine vehicles. Applications range from steady
and unsteady (seakeeping) performance predictions for America's
Cup and other grand prix race sailing yachts, to prediction of unsteady
hydrodynamic loadings for structural analysis of oil tankers.
||USAERO uses potential
flow and boundary layer methods with a time-stepping procedure for
arbitrary motions assures timely and cost effective assessments
of unsteady surface pressures and loads. USAERO calculates the transient
aerodynamic characteristics of complex configurations in arbitrary
motion. It is based on a time-stepping procedure, which allows relative
motions of configuration components. As integral potential flow
and boundary layer methods are the basis of this CFD software, the
aerodynamics solution is only required on the boundary surfaces
for each time step and requires only surface meshing.
||VisualSMP is a suite of tools used
in the prediction and analysis of a ships seakeeping characteristics.
Included in VisualSMP is the SMP95 strip theory based frequency
domain seakeeping program, the SEP96 seakeeping analysis program,
the STH97 time history program, and the SWMP96 SWATH seakeeping
program, all developed by the US Navy. VisualSMP adds a graphical
pre- and post-processor, together with tools to simulate and visualize
the motion of the ship in a seaway.
codes developed by M.I.T. that can work with MultiSurf models. AeroHydro
has provided geometry support for the WAMIT Joint Industry Project
at M.I.T.'s computational Hydrodynamics Facility, and has supplied
advanced modeling and panelization capabilities to WAMIT. HIPAN
uses B-spline geometry and singularity distributions, and require
quite different geometric input from WAMIT.
||WaveLoad is a powerful hydrodynamic
analysis tool for ships and offshore structures in the frequency
and time domain. By accurately predicting wave loads and structural
behavior in various sea states, WaveLoad increases the safety and
performance of ships and offshore structures.
