 SHIPFLOW 6.3.01

SHIPFLOW version 6.3.01 is now available for downloaded from our home page, Here are the major news:

  • The computational times for the SHIPFLOW RANS/VOF solver are reduced considerably
  • The updated version of SHIPFLOW MOTIONS is improved in terms of accuracy and computational speed
  • SHIPFLOW Design is based on CAESES 4.2.1

See article SHIPFLOW 6.3 for more information.

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.


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.

Workshop on ship performance

 Seoul, Korea April 14, 2016

CFD applications

In this workshop we will demonstrate how Computational Fluid Dynamics (CFD) can be used to optimize the ship performance. The first part of the workshop will cover computation of ship motions and added resistance in waves, and the second part will cover automatic shape optimization for minimum delivered power. The presenters will show examples of these applications and discuss how it can be implemented in the design process using the new efficient techniques in SHIPFLOW 6.

Application of SHIPFLOW MOTION to hull optimization

Nowadays most of the ship hulls are optimized in calm water. However, reducing added resistance in waves can be the key to the optimum performance of a ship. In the second article we show a comparison of two bow types for a typical VLCC hull form using CFD. Calculations have been performed with MOTIONS module of SHIPFLOW 6.1

The article is called Performance in waves – part 2 and can be found in under the menu Cases.

Article on SHIPFLOW MOTION validation

The first published article in a series of articles on ship motions and resistance in waves. It contains a validation case based on KVLCC2. Calculations have been performed with MOTIONS module of SHIPFLOW 6.1

The article is called Performance in waves – part 1 and can be found in under the menu Cases.
