Catamaran seakeeping software

And there it stopped. But it was also the tool used to design the first active catamaran stabilization systems and predict their performance in a seaway. Incats, Westamaran, Batservice, etc.. We later developed a monohull program too.. In fact, "We" is not really correct; Dr. Higdon developed the monohull program for us and I had nothing to do with that one at all.

Extensive environment input options: sinusoids, spectra, data, ranges, spreading, and flexible sampling. Ability to specify any loading condition to an exceptional level of detail and include all inertial properties. Ability to run many, many cases with little effort and maximum repeatability. Robust and flexible damping model: numerical, experimental, or a mix of both.

Bilge keel and skeg appendage support. Full-featured data IO: everything SK computes is accessible. LIB macro library means you can use all of the data SK creates for powerful post-processing. Powerful and unique SEA DATA mode computes motions using external RAO or hydrodynamic data allowing for complex geometry, rapid re-evaluations in different seaways, custom modification to coefficient matrices, and more.

Full or partial hydrodynamic coupling and the ability to analyze asymmetric conditions. Maintained, supported, user driven. SeaKeeping Features The module offers users the following features: Integration with GHS command language and run files allows unmatched flexibility Minimal syntax makes setting up a seakeeping analysis quick and easy Available Acceleration Transform Wizard makes it easy to compute deck-parallel and deck-normal acceleration components with or without the gravitational acceleration term for cargo and sea-fastening applications Available Long Term Statistics Wizard provides a powerful tool for the input and manipulation of wave scatter data: compute statistics, set up an analysis, and derive insight for transportation, route-planning, and sea-fastening design.

Use of GHS geometry files. A, B, and C's Wave Data: includes wave sample characteristics such as periods, frequencies, spectral ordinate, sample amplitudes, etc. Variance Data: includes response variance m0, m2, m4 for all modes and all Critical Points Statistics Data: includes response statistics such as periods, RMS, average, significant, and extreme amplitudes Tank Data: includes tank moments for any roll tanks Dedicated SK.

LIB seakeeping macro library provides useful macros and automated data file parsing to make data easily accessible as variables, and allows for powerful post-processing SEA DATA mode provides flexbility and efficiency allowing SeaKeeping to run on pre-existing RAO or hydrodynamic data, allowing for rapid re-evaluation in different seaways or modification of coefficient matrices Full-featured and comprehensive report file includes all RAO and phase angle tables and plots, response statistics, continuous and sampled spectra tables and plots, summary tables, derived response tables, and polar plots Don't see a specific feature on the list?
