Makers of MOSES - The Final Answer in Marine Simulation
What Is New In Rev 6.01

Web Site:

Our web site and consequently the help desk has been changed. Most of the change is in appearance, not substance. Hopefully this will lead to better navigation.

The Installation Macros:

The Automated Jacket/Deck Installation macros have been completely rewritten. The previous design was that there was a cif file (and consequently a run) for each type of analysis. Now, all of the analyses can be performed in a single run. As a result, you have a single code check for all phases of the installation. Click Here to see the documentation.

Local Element System:

The definition of the local element system for a plate has been made consistent with that of a beam; i.e. one now has two SAV vectors which are used with the element special direction to define the local system. The default for these two vectors is via option on &MODEL_DEF: -DIR_BEAM and -DIR_PLATE. The first of these replaces directly the old -STGAXIS option which has now been removed from the documentation. Both beams and plates now have a new option -DIR_LOC which can be used to completely redefine the SAV vectors for the element. Click Here to see the documentation.

Summaries:

Several changes have been made in &SUMMARY Menu. In particular, the REST_SUM command has been eliminated. Also, the BEAM_SUM type of SECTION has been moved to the CLASS_SUM command. This summary now has information about the stiffeners for the section. A new type, TUBTANK, has been added to COMPARTMENT. Finally, the PLATE_SUM has been changed to report information about the reference node and the local coordinate system. Click Here to see the documentation.

String Functions:

Several options have been added to existing string function and a new string function has been added:
  • Six new types, V_P2B, V_B2P, L_P2B, L_B2P, F_P2B, or F_B2P have been added to &V_TRANSF. Click Here to see the documentation.

  • Three new types, UNIT_VECTOR, MEAN and SORT, have been added to &NUMBER. Click Here to see the documentation.

  • Two new types, OVERLAY and REPEAT, have been added to &STRING. Click Here to see the documentation.

  • New types, C_FILE, C_PATH, C_IFILE, C_IPATH, C_CFILE and C_CPATH have been added to &INFO. Click Here to see the documentation.

  • Several new types:, CURRENT, MAX_CB, MAX_BUOYANCY, B_WEIGHT, B_CG, B_RADII, B_MATRIX, A_WEIGHT, A_CG, A_RADII, A_MATRIX, D_WEIGHT, D_CG, and D_RADII and D_MATRIX have been added to &BODY. Also, DEFWT, DEFWT_CG, DWCG, WEIGHT, CG, RADII have been removed from the documentation. Click Here to see the documentation.

  • A new type, CURRENT, has been added to &PART. Click Here to see the documentation.

  • New types PART and NEAREST, has been added to &POINT. Click Here to see the documentation.

  • A new string function, &CLASS, has been added that provides information regarding classes. Click Here to see the documentation.

General Changes:

  • A new internal command, &ERROR has been added. Click Here to see the documentation.

  • Three new types of status have been created: B_MATRIX, A_MATRIX, and D_MATRIX. These produce report of the basic, apparent, and defined weight matrices.

  • One can now issue &STATUS PILE to obtain soil and soil multiplier information about piles.

  • One can now use CDRs in pictures. In general, any place you can use RATIO, you can now use CDR.

  • A new command, GEOMETRY has been added to the connector Design Menu. This allows one to get the current geometry (similar to &STATUS DG_CONNECTOR) in the Disposition Menu. Click Here to see the documentation or Here to see an example.

  • One can now connect a spring buoy to a pendant line. Click Here to see the documentation or Here to see an example.

  • Two new options: -CROP_FOR_LEGEND and -CLEAN_LINE are available on the PLOT command. Click Here to see the documentation.

  • The #TABLE load group attribute has been changed so that the point of application is now defined with #TABLE instead of within the table definition. Now a table can be reused at different locations. The old was still works. Click Here to see the documentation.

  • One can now have a user defined load set which varies with time. Click Here to see the documentation or Click Here to see a sample.

  • A new option for TDOM, -EQUI, has been added that uses the time domain to solve for equilibrium positions. Click Here to see the documentation.

  • Post processing of points has a new report type of of GS that provides the dynamic "G" loads for selected points. Click Here to see the documentation.

  • A new command &EMIT, has been created that is useful for emitting MOSES modeling commands. Click Here to see the documentation.

  • Under the &SURFACE menu, a new option has been added to the EMIT command, -POINTS, which will emit the points previously created, without a corresponding &DESCRIBE BODY or &DESCRIBE PART command. Click Here to see the documentation.

What No Longer Works:

  • The FRQMEAN load case resulting from lcase -rao is now named FRQMEANA to be consistent with the RAO load case names.

  • The LCASE word for &STATUS no longer works. Use S_CASES instead.

  • The REST_SUM in the &SUMMARY MENU has been removed. A &STATUS of PILE can be used to obtain pile information.

  • The out of date commands &M_ANCHOR, &LWAY, &CO_STAT, and &C_LENGTH have finally been removed. If one gets an error, he should replace these with &CONNECTOR.

  • The TYPE of SECTION is no longer valid for the BEAM_SUM command. It has been replaced with SECTION on the CLASS_SUM command.

  • The way in which continuation is handled has been changed. Before if one have a line which was continued and he wished to comment it out, each line must have been commented. Now, only the first one need be done. More precisely, everything after a comment character is ignored except a continuation.

  • The LCASE command which uses a lset name and a multiplier has been removed. This command was inconsistent with the new ability to specify the temporal variation in an lset.

What Answers Will Change:

The loop variable is now undefined upon exit from a loop. Thus, if one had 
    &loop k 1 3
    &endloop
    &type k = %k
you will now get an error that k is undefined.

The way in which the "chord" is defined for joints has changed. In the past, the largest diameter tube was proclaimed the chord, regardless of whether or not there was an element on the other side. Now, the pair of elements with the largest diameter is the chord. Of course, the pair must be on opposite sides of the joint and have centerlines in the same direction.
