What NVS can do

Don't take the capability on faith. See it worked through.

The fastest way to judge a solver is to watch it take on a real problem. Below are three analyses an engineering team actually pays for: what the question is, how NVS approaches it, the published method it rests on, and what you get back. Same solvers that run in production today; no slideware.

Worked examples

Three problems, start to finish.

Seakeeping & hydroelasticity

SurfWAST

The problem: A design office has a floating structure (a hull, an offshore platform, a floating solar array) and needs to know how it moves in a seaway and what wave loads it must survive, in the form a classification review will accept.
How NVS approaches it: SurfWAST computes the response amplitude operators across the full six degrees of freedom, the added mass and damping, and the wave-induced loads, in regular and irregular seas. Where the structure is large or flexible enough that it bends with the waves, the analysis runs hydroelastic rather than rigid-body, so motion and structural response are solved together, not bolted on afterward.
The method behind it: NVS handles the wave–body hydrodynamics through the Fourier–Kochin theory, developed and tested for floating structures in peer-reviewed work, with the boundary-element accuracy (including the suppression of irregular frequencies) studied in further published papers.The papers behind it
What you get back: RAO curves and motion statistics for your sea states, the wave-load envelopes a structural check needs, and, for realistic extremes, a probabilistic, extreme-value treatment rather than a single design wave.

Vibration & vibroacoustics

SubVAST

The problem: For work where acoustic stealth is the whole point, a team needs to know the noise a submerged structure radiates into the water under propeller and machinery excitation, before it is ever built, while the design can still change.
How NVS approaches it: SubVAST runs the chain end to end: a modal and frequency-response analysis of the structure, the vibration driven into it by propeller and machinery, and the acoustic field that vibration radiates into the surrounding water, with fluid and structure coupled throughout, down to shallow-water propagation.
The method behind it: The vibroacoustic method, a coupled structure-and-propeller system radiating into a fluid, was built and reported in peer-reviewed studies, including the self-propulsion case, by the same team that develops NVS.The papers behind it
What you get back: The structure's modal and frequency response, the radiated acoustic field and signature for the operating conditions you specify, and the evidence to compare design options on noise, early, where a change still costs little.

Hydroelasticity & FSI

SurfWAST · SubVAST

The problem: A structure does not vibrate in air the way it vibrates in water. A tank wall with liquid behind it, a large floating body that flexes, a shell with fluid running through it: get the fluid coupling wrong and the natural frequencies, the mode shapes, even the stability are wrong with it.
How NVS approaches it: This is the physics NVS was built on. The solver models the structure together with the fluid it touches (contained, surrounding, or flowing) using boundary elements coupled to the structural model, so the wetted natural frequencies, mode shapes and dynamic response come out of one consistent analysis. For flow-induced cases, it carries through to dynamic stability.
The method behind it: The fluid–structure coupling at the core of NVS comes straight from the team's foundational hydroelasticity research (partially filled and submerged structures, shells containing flowing fluid, and the dynamic stability of plates in axial flow), a body of peer-reviewed work built up over years.The papers behind it
What you get back: Wetted natural frequencies and mode shapes that account for the fluid, the dynamic response under your loading, and, for flow-induced problems, the stability margins that tell you where the design is safe.

On the way

The same problems, straight on your CAD geometry.

The examples above run today on classical finite- and boundary-element solvers. In development is an isogeometric core that takes the same hydroelastic and vibroacoustic physics directly onto your CAD geometry: no meshing step, no precision lost in translation. The method is already proven in published research; the product side is an active research preview.

The research preview

Now bring the one that's actually on your desk.

These three show the shape of the work; yours will have its own. Send us the case and we will show you how NVS would take it on, or, when the cloud preview opens, you will be able to set it up and run it yourself.
