 SHIPFLOW 6.3

We are happy to announce that the latest release of SHIPFLOW is available. Version 6.3 can be downloaded from our home page, www.flowtech.se. Customers in the maintenance program can request a new license file for the new version. We have added many new features that we think you will enjoy using. Here are the major news:

  • SHIPFLOW Wizard
  • New version of the VOF RANS solver
  • New version of MOTIONS
  • Video tutorials and application examples

SHIPFLOW Wizard

The users of SHIPFLOW can with the new release enjoy a simplified program configuration to set up and run computations. The configuration follows the familiar naval architect conventions from the import of the ship geometry in IGES-format to specification of the initial position, speed and scale. Instructions to control the type of simulation is reduced to a minimum. In addition a result driven configuration wizard has been developed to guide the user to configure resistance, self-propulsion and added resistance simulations. The handling of convergence check and parallelization are automated. This in combination with the automatic grid generation for the potential flow and the RANS solvers minimizes the user dependencies of results and the total time to achieve the results.

SHIPFLOW RANS

The viscous free surface solver XVOF is reworked to improve robustness and accuracy. The new version has been validated for several well established validation cases and other commercial vessels with excellent results.

SHIPFLOW MOTIONS

MOTIONS has been improved in several aspects. Limiters for steep and breaking waves have increased the robustness. Changes in the treatment of the outer boundaries makes the program less sensitive to the time step size and allows for larger time steps. The new version has been validated for several well established validation cases and other commercial vessels with excellent results.

Tutorials and application examples

The collection of examples has been updated to make it easier for users to find recommendations for a large number of ship types and simulations. Several of the examples are based on well documented test cases that can be used for validating SHIPFLOW and serve as template for similar ships and applications.

The tutorials and documentation have been updated to include the new features. Three video tutorials for using the new SHIPFLOW Wizard for Resistance, Self-propulsion and Added Resistance in Waves applications are published on FLOWTECH’s Youku and YouTube channels:
