SHIPFLOW 6.6 includes developments and refinements in the following areas:

- Full scale power prediction

- Roughness effects

- Parametric appendages

- Inbuilt Wageningen B-Series propeller geometry 

- Twin-skeg gridding

- Free sinkage and trim calculations with VOF solver

- Appendages and selfpropulsion with VOF solver


SHIPFLOW 6.5 intorduces a new evaluation method for the wave resistance computed by XPAN. The new predictions give more reliable results for a wide range of ships including container vessels, tankers and bulk carriers. This improvement as well as other small changes and bug fixes makes it a highly recommended update for the users.

Parametric roll

The video shows the motion of the DTC container ship experience parametric roll. The prediction was produced with the release 6.3 of SHIPFLOW MOTIONS.

In this simulation the wave encounter frequency is approximately twice the natural roll frequency and the wavelength of the encountering wave is approximately equal to the ship length. The ship was given an initial roll of one degree in order to trigger the roll. No viscous damping was added in this case.


Added resistance in regular head sea wavesSHIPFLOW 6.2

The major news are:

  • Improved accuracy of ship motion and added resistance in waves
  • Improved MOTIONS robustness
  • Added user defined damping coefficients e.g. roll damping
  • Multiple improvements to overlapping grid algorithm

Accelerate SHIPFLOW Simulations on Rescale

In this webinar we demonstrate how SHIPFLOW users can benefit from using Rescale’s on-demand, HPC cloud platform.

CFD is used extensively for the hydrodynamic design of ships, including evaluation of resistance, delivered power, added resistance, or even for automatic hull shape optimization. However, limited local computing resources and deadline constraints can limit the CFD scope for these projects. Whether working with a few large computations or many smaller computations in an optimization, access to additional resources in the cloud can be the solution.
