    What's new in version 10.13?

    MOSES 10.13 now allows naval architects and specialist engineers to evaluate stability during a launch analysis with the automated installation tools. The stability evaluation is carried out as per DNVGL-ST-N001 Section 13.6.4. To implement this new feature users need to add the -STAB option in the INST_LAUNCH command.

    The required syntax is as follows:
    INST_LAUNCH -STAB WINDT WINDL SLD_STP
    where WINDT and WINDL are the wind speeds before launch sliding begins and during sliding respectively. SLD_STP is the slide step at which stability is to be evaluated.

    The stability data are tabulated in the log file in the following format:

    MOSES will check the following two criteria during launch:

    1. Evaluate and report if the static stability range is greater than 15 + (10/GM) , or greater than 20 degrees, whichever is higher.
    2. The ratio of the area under the righting moment curve (from upright to the second intercept with the wind heeling moment curve, or the downflooding angle, whichever is less), should not be less than 40% in excess of the area under the wind heeling moment curve between the same angles of inclination;
      [​IMG]
      i.e. AreaGZ ≥ 1.4 × AreaHA
    If both of the above criteria are met, MOSES reports that the stability requirements are met.

    What's new in version 10.14?

    MOSES data files are forward and backward compatible between most versions of MOSES. Where backward compatibility has been broken, the option to export to earlier file formats is provided in the new version.

    Version 10.14 of MOSES includes a Technology Preview of the new MOSES Executive. Installed alongside the classic versions of the MOSES applications, the Executive aims to replace and build on the functionality of the existing classic version of MOSES.

    As part of the development of the new MOSES Executive some inconsistencies were noted in the calculation of motions and forces using strip theory. These inconsistencies have been resolved, but users will notice that there have been some minor changes to the results from version 10.13 after a strip theory analysis. Typically these changes are manifested as rounding differences in the results.

    Some of the features of the MOSES Executive include:
    • A unified editing, analysis and post processing interface
    • A project view containing all files referenced in a given analysis
    • An inbuilt editor with context sensitive highlighting, access to help for a given MOSES command (via the F1 key) and easy commenting of code sections
    • Advanced data processing features including interactive graphs plotted from data produced whenever a REPORT command was issued
    • Updated model viewing capabilities, including the ability to directly record *.avi files from a desired view point

    What's new in version 11.00?

    Fri, 21 Dec 2018 03:51:08 GMT

    The MOSES development team is pleased to announce the release of MOSES v11.00. This is the first version of MOSES with Bentley’s new CONNECT Licensing.

    This version of MOSES includes bug fixes, minor changes and the following enhancements:
    • A new command, CAT_PLOT, has been added to allow users to plot the shape of a bottom catenary.
    • A new option, -I_T2, has been added to the STAB_OK and KG_ALLOW commands. This allows for a check to be made on the minimum heel angle of the second intercept between the heeling and righting arm curves, as required by some stability regulations.
    CONNECT Licensing is Bentley's new process for product activation, enhancing our users' digital workflows and improving our licensing capabilities with features such as:
    • License alert notifications when you are approaching a custom usage threshold
    • Replacing site activation keys with user validation, enhancing security around your Bentley licenses and subscriptions
    Traditionally, product activation has been through an activation key that an Organization distributed to all of its users. With CONNECT Licensing, product activation is managed by user sign in through the CONNECTION Client, which is installed on each machine that uses Bentley applications. This offers a more secure and manageable system as it offers usage alerts, notifying your users when they are about to reach a certain usage limit set by the Administrator.
