Notilus CFD — marine CFD analysis for Rhinoceros
← All products

Marine CFD,
run inside Rhinoceros.

Model a hull, set a speed, click Run — get calm-water resistance, wave pattern, hull pressures, running trim and a first propeller match.

— What's inside

The whole hydrodynamic loop, inside Rhino.

Resistance curves, wave patterns, hull pressure maps, running trim and a first propeller match — every result delivered on your own hull model, inside Rhinoceros.

Hull straight from Rhino
01 · Setup

Hull straight from Rhino

Pick the hull surface, give it a draft and a speed range, and get results for the hull you actually designed.

Project data in one place
02 · Project

Project data in one place

Vessel, units, main dimensions, notes and loading conditions are saved with the project, so every run starts from the same data — half load and full load side by side.

Marine-tuned meshing
03 · Meshing

Marine-tuned meshing

Tight chines, spray rails and hard flare are captured as drawn, so every number reflects the real shape of the hull.

04 · Solver

Free-surface calm-water run

Every speed in the range becomes a full calm-water result, with wave-making and viscous resistance taken from the actual flow around your hull.

Live force convergence
05 · Monitoring

Live force convergence

Pressure and friction force histories plotted while the run is still going, so you can tell a converged answer from a wandering one at a glance.

06 · Results

Resistance across the speed range

Total resistance built up speed by speed and split into pressure and friction components — the curve a hull decision actually rests on.

Wave pattern in the viewport
07 · Results

Wave pattern in the viewport

Free-surface elevation and the Kelvin wake shown in Rhino as a mesh you can rotate, section and put in a client presentation.

Pressure map on the hull
08 · Results

Pressure map on the hull

Pressure distribution baked onto the hull surface. Spot the slam-prone forward sections, separation behind a hard chine, and where the shape is fighting the water.

Running trim & sinkage
09 · Motion

Running trim & sinkage

Running trim and sinkage at every speed — an indication of how the hull will actually sit under way.

Engine selection
10 · Propulsion

Engine selection

Set the propulsion type, the number of engines and their rating, then the wake fraction and thrust deduction that go into the propulsive efficiency.

Empirical sanity check & propeller curves
11 · Cross-check

Empirical sanity check & propeller curves

A Holtrop-Mennen estimate sits beside every run, and Wageningen B-series open-water curves turn the resistance number into a first propeller pick.

— How it fits

CFD in the marine engineering pipeline.

  1. Model Hull straight from Rhino

    Pick the hull surface you designed and set a draft and speed range. No export, no remodelling.

  2. Mesh Marine-tuned mesh

    Chines, spray rails and flare are captured as drawn, on a mesh tuned for marine hulls.

  3. Run Calm water, every speed

    Resistance, wave pattern, hull pressures and running trim across the whole speed range.

  4. Decide From resistance to propeller

    Engine settings and Wageningen B-series propeller curves turn the resistance numbers into a first propeller pick.

Notilus CFD in the suite.

Notilus CFD is part of an end-to-end marine engineering toolset. These plug-ins pick up the hull once its hydrodynamics are settled.
