Makers of MOSES - The Final Answer in Marine Simulation
What Is New In Rev. 5.05

General Changes:

Since this is quite early in the release cycle, it is almost impossible to predict the general nature of this release, but it is anticipated that it will be a minor one.

What No Longer Works:

For the moment, everything from the old release will work here with no modification.

What Answers Will Change:

The manner in which strip theory panels are mapped to points has been changed. In the past, the loads on all segments were mapped into all of the points of a station. This has been changed to be consistent with diffraction theory, i.e. the loads from a segment will now be mapped to the closest two points. As a result, any structural analysis of flexible vessels which used strip theory will change for the better.

Pulleys:

Over the years, there has been an occasional need to model a pulley. Two instances spring immediately to mind: first when one has a line which passes through a pulley and back to a body, and second to correctly model the fact that an anchor line passes through several pulleys before it begins its decent to the ocean bottom. In REV 5.05, we have added the concept of a "Pulley Assembly" which can account for these effects. You can click here to see an example of how these are defined, or you can click here to read the documentation.

Panel Pressures:

One can now have information about the frequency response of the average pressure on panels. These pressures can be written to a file for use elsewhere, or you can post-process them directly. You can click here to see an example of how to get pressure response, or you can click here to read the documentation.

Panel Mapping:

In the past, our automatic meshing scheme work quite well for plate models, but often had problems mapping things correctly when a vessel was defined via a stick model. To minimize these difficulties, we added several options to the M_PAN_FIX command. You can click here to read the documentation.

Miscellaneous Changes:

The &REP_SELECT command now has the options -MAP and -PANEL for selecting map names and panel names. The -MAP option works on the &STATUS MAP and &STATUS N_MAP commands. The -PANEL option works on the HYDRO_SUM PANEL command.

The PICTURE command has a new option, -SHRINK which causes panels to be contracted toward their center a small amount. This is useful when looking for missing panels or when using color to select in panel pictures.

The plate stress report has been changed. In the past, we reported membrane stresses and bending moments/length. Now, we report membrane and bending stresses.
