Sometimes we're asked the difference between a Resistance simulation and a Powering simulation (sometimes referred to as Self-propelled), and why one is...

The standard version of Orca3D Marine CFD predicts the calm water resistance and powering performance of ships, yachts, boats, and planing vessels by simula...

This short 4-minute video walks through the steps of enabling streamlines on your model. It also shows the steps to "clean up" the view to remove ...

Orca3D Marine CFD automatically adds external forces and moments to your simulation to account for things like gravitational force and propulsion forces fro...

By default the marine simulations performed in Orca3D Marine CFD treats the wall boundaries corresponding to the hull, deck, and other model surfaces as per...

With Orca3D Marine CFD, you can easily create a Python script to automate the process of running multiple simulations that consist of the same vessel and co...

By default the planing template accelerates the boat to full speed in 0.1 seconds, which is clearly not realistic. We do this in order to reach the steady e...

If your model is hitting the limits for maximum heave or pitch (which you can see in the time history plots), you may need to adjust the limits. Sometimes t...

You can add a wind velocity to the simulation. It is not built into the marine template currently so you need to do it manually. Note that if your wind dire...

Steady State Convergence An important consideration when using any CFD tool to analyze vessel performance is whether a simulation is "converged."...
