Marine / Naval

NUMECA is now Cadence


Cadence believes naval architects and engineers should utilize the best tools for the job, that's why we have created CFD software that functions as a virtual towing tank, with built-in automation features, designed specifically for the marine industry. 

Perform resistance, propulsion, sea-keeping and maneuvering calculations effortlessly, thanks to our simple-to-use, step-by-step process, built on years of industry experience.  Set-up of calculation matrices for different speeds, angles, sea conditions or even geometrical variations can now be accomplished in a completely automated way. Engineers can evaluate full-scale performance, in 3D, with absolute certainty; no extrapolation from scale models is necessary.

Further, brand-new solver technology allows users to perform hydraulic calculations as fully-transient, with no pre-processing steps. Obtain a highly-accurate solution just by loading a geometry and hitting the "solve" button!


Application dedicated CFD software

Cadence’s solutions enable fully-automated, virtual naval architecture and marine design with tools such as:

  • A marine dedicated, flow-integrated environment for free-surface flow analysis including specific post-processing for the offshore and marine industries 
  • Drastically reduced engineering time for complete CFD simulation set-up, thanks to the C-Wizard
  • Fully-automated mesh generators for high-quality, multi-block structured meshes or fully hexahedral unstructured meshes.
  • Advanced mesh management capabilities for complex motions: sliding grids, overset grids, and our unique-to-market Adaptive Grid Refinement technique
  • Advanced cable dynamics module for tug ships, floating offshore platforms, and many others.

Solutions can be rolled out on premises, On-Demand via dedicated HPC Cloud Computing Resources or a powerful combination of both.

Automatic set-up of the CFD chain with C-Wizard

The new C-Wizard, incorporated in FINE™/Marinedrastically reduces engineering time for complete CFD simulation set-ups through an automated process.  

It uses all the scripting tools from the interface to automatically set up different applications, such as:

  • Resistance at low and high Froude numbers
  • Sea-keeping
  • (Self-)propulsion
  • Trim optimization
  • Open water propellers

All kind of boats are eligible for the C-Wizard: tankers, containers, high speed crafts, sailing or luxury yachts, even hydrofoils and open water propellers.

No need to spend time on setting numerical parameters. By specifying the physical inputs only, users receive a complete definition of the required simulations, including numerical aspects.

Forget about CAD repair thanks to AutoSeal

AutoSeal is the fastest, most innovative approach for CAD preparation on the market today​.  

Poor quality CADs and highly complex structures require a lot of manual input to result in a good quality mesh.

Cadence’s AutoSeal offers the ability to automatically prepare geometries for CFD analysis in near real-time. For example, it was taking skilled engineers from Honda Automotive one week to clean and fill the holes in their CR-V cab geometry. With the simple installation of AutoSeal, Honda now does this in 1 hour with a 100% success rate (read about the details here). It was a radical improvement to their workflow that was implemented in under a week. 

This technology works for everything: complete cars, ship (super)structures, combustion chambers, offshore platforms,... whatever geometry you have, including CAD and STL, even geometries coming from 3D scans.

"If there's one thing that's going to win the America's Cup for us, that's going to be simulation."

Dan Bernasconi - Head of Design ETNZ

"It's really important to get the calculations exactly right, that's why we chose FINE™/Marine, because we know we can trust it. "

"And to be able to turn around designs really quickly, so that we have lots of opportunity to make improvements before we put anything on the water."
