• A Discussion on the OMEGA Option in Equilibrium Calculations in MOSES


    This document presents a discussion on the -omega option that is part of the &EQUI command. The &EQUI command in MOSES computes a static equilibrium position with a modified Newton method.  Also presented is an example when the -omega option in the &EQUI command is used to reach equilibrium.

    Basic Theory

    You can find a good description of the Newton method on Wikipedia.  The article in Wikipedia shows…

  • Working with Units in MOSES

    This document explains how to set up and interchange the working units in MOSES.

    Two sets of files are used to demonstrate the unit definition and units interchange to assess the longitudinal strength of a barge. The two sets of files can be found on ...\hdesk\runs\samples\how_to directory.

    MOSES v10.14 was used in generating results for this work.

    Specify Analysis Units

    The analysis units are specified with the &DIM…

  • Brief Note on Inertia & Damping Coefficients in MOSES

    This document explains how the added inertia coefficients and linearized damping coefficients are calculated and reported in MOSES. Often asked questions are also discussed at the end of the document.

    MOSES v10.13 was used in generating results for this work.
