Innovation & Quality

NUMECA marine solutions are very well suited for propellers related analysis like open water and ship performances, and local phenomena (cavitation, pressure pulses, etc.). NUMECA tools can be used to mirror tank test but also sea trials thanks to adapted wave modeling. 

We help you with fluid dynamics propeller simulation with different level of complexity, based on a uniform thurst, open water data or real propeller geometry including energy saving devices.

Use our optimization engine to optimize the propeller blades geometry to get better performances, increase the ship speed and/or reduce the fuel consumption.


A fast, complete and easy-to-use solution dedicated to propellers.

  • The leading software for marine applications. 
  • Ready-to-use and automatically coupled to the NUMECA optimization engine.  
  • Highly accurate and fast software with top-notch meshing of the propeller thanks to a structured meshing tool.
  • Wizard with dedicated self-propulsion and open water propeller modes.


Join us during our paper presentation to discover propellers simulations applications and to discuss with our team.

About the conference

Propellers - Research, Design, Construction & Application will highlight topics like contra-rotating propellers, impellers, twisted rudders, vane wheels, pre- and post-swirl stators, rudder bulbs and rudder fins, cavitation: erosion and noise, podded propulsors, and nozzles.

Especially during the last decade, the economic circumstances have made the energy/fuel savings a decisive competitive factor and environmental concerns have become one of the most important issues the maritime industry is facing nowadays.

Those challenges are being tackled through research and development in the design and construction of propellers in all applications, making a significant contribution to increasing efficiency and reducing emissions.

Influenced by IMO regulation on energy efficient design index (EEDI), the demand of energy saving devices (ESDs) is expected to keep growing. Its design requires a deep knowledge of the flow behaviour in the aft area of the vessel and highly advanced CFD simulations are required in order to properly characterise the hydrodynamic efficiency due to the propeller/hull interaction.
