SHIPFLOW version 6 is released!

SHIPFLOW 6 comes with a new module for computing ship motions in waves and the SHIPFLOW RANS solver is up to 10 times faster than its predecessor.

03 September 2015

SHIPFLOW MOTIONS is a new flow solver for computing ship motions in waves. It is a time accurate fully non-linear boundary element method which can be used to compute ship motions and added resistance in regular and irregular waves as well as wave resistance, sinkage and trim in calm water. Typical results are time series and response amplitude operators. We believe that the method will be a useful tool for ship designers with higher accuracy than traditional potential flow methods while at the same time being faster than the available RANS methods.

The SHIPFLOW 6 RANS solver XCHAP is now up to 10 times faster than its predecessor (version 5.2). A resistance computation can be run within 15 minutes and a self-propulsion simulation within 1 hour on a workstation. The increased solver performance and the efficient self-propulsion capability in SHIPFLOW makes automatic shape optimization of ship sterns feasible for ship designers. The delivered power can be optimized with self-propulsion simulations taking the two, often conflicting, aspects of resistance and propeller efficiency directly into account. SHIPFLOW 6 and CAESES* have been used successfully for stern shape optimizations of mono and twin-skeg hulls.

"We are thrilled to offer the new efficient capabilities for optimizing the ship hull to reduce the delivered power and improve the performance in waves", said Leif Broberg, managing director of FLOWTECH International AB. "These optimizations can now be used by our customers in their ship design process and we hope that it will contribute to more energy efficient and safer ships in the future".

FLOWTECH International AB with its product SHIPFLOW is the market leading developer and supplier of Computational Fluid Dynamics software packages for the Marine Industry. The package is designed to streamline the hull form, appendage and propulsion design process with a clear focus on optimisation in order to minimize energy consumption.

SHIPFLOW stems from long term research at FLOWTECH in close cooperation with SSPA and the Department of Shipping and Marine Technology at Chalmers University of Technology. Much of the development has been moved forward by joint projects with SHIPFLOW users and/or European and Nationally financed projects.

The number of licenses has grown steadily since the first version, SHIPFLOW 1.0, was released in 1991. Top shipyards, consultants and universities are among the SHIPFLOW users. Developed by naval architects, physicists and numerical analysts the software is optimised for ship hydrodynamics design. Specialisation means SHIPFLOW is efficient and user-friendly. Grids are automatically generated, resistance and propulsion data are presented in the naval architect's way and the solvers are adapted for hull geometries. Over the past twenty five years SHIPFLOW has developed into the world standard for ship hydrodynamics CFD.

*Since 2007 FLOWTECH has had a close cooperation with Friendship Systems. Friendship Systems develop and market CAESES which is fully integrated with SHIPFLOW creating a very powerful tool for simulation driven design. SHIPFLOW Design is a subset of CAESES giving the user a complete pre and post processor but missing out on most of the optimisation and CAD tools which are available in the complete CAESES.
