SP80’s partnership with Orca3D and Simerics: a step towards hull’s optimization.

April 5, 2020

While the world is tearing apart due to the unprecedented COVID-19 pandemic, our team is still working as hard as before to keep the three years SP80 project objectives. Now that teleworking is mandatory almost worldwide, SP80’s partnership with Orca3D and Simerics has enabled the possibility for faster and easier CFD computation from home.

Orca3D Marine CFD is the result of a collaboration between two American software specialists: Orca3D and Simerics Inc. It combines naval architecture (Orca3D) and CFD (Simerics) softwares. Its designers have bet on the facility and user-friendly aspects for their product, allowing quick alternative designs simulations without the long learning curve typically associated with CFD.


“Orca3D Marine CFD is providing additional knowledge about how to make the SP80 sailboat go very fast without the past requirement of having a PhD in CFD” insured Rich Moore, Executive Vice President, Strategy, OEMs, Partners, at Simerics, Inc. For us, its main asset will be the facility and velocity of CFD hull simulations with respect to other CFD softwares. Furthermore, it will particularly allow to save time when defining a set-up and also to quickly study several shapes and parameters.

“Orca3D Marine CFD will be essential for our future work” commented Anaëlle Manon and Charles de Sarnez, two members of the SP80 fluid dynamics team. We will start by using it for the Velocity Prediction Program data generation. It will afterwards allow us to simulate different parameters’ influences, such as pitch, yaw or speed on the hull we already have. The results are going to be used to improve the VPP’s precision, which will in turn permit a study on the hull’s shape optimization.
