Printer Friendly Post-Processing Drafts and Points Post-Processing Drafts and Points

One class of command is always available within the Process Post-Processing Menu - the ones which deal with Interest points and Draft Marks. There are two commands available: DRAFT and POINTS. After the results have been computed, MOSES places the user in the Disposition Menu so that he can dispose of the data.

MOSES is instructed to compute the draft readings along the draft marks selected by :DNAME with the command:


     DRAFT, :DNAME,  -OPTIONS

and the only option is:


     -EVENTS, EVE_BEGIN, EVE_END, EVE_INC

Here, EVE_BEGIN and EVE_END are the beginning and ending event numbers for which the results will be computed, and EVE_INC is an event increment. The corresponding form of the REPORT command is:

     REPORT, -OPTIONS

The only option available for reporting is:


     -EVENTS, EVE_BEGIN, EVE_END, EVE_INC

The POINTS command instructs MOSES to compute the location, velocity, motion, and acceleration of the points selected by :PNT_NAME. Here, motion is the vector from the global location of a point the last time the command &DESCRIBE INTEREST was issued to the current position of the point. The form of this command is:


     POINTS, :PNT_NAME,  -OPTIONS

The options are:


     -EVENT, EVE_BEGIN, EVE_END, EVE_INC

     -MAG_DEFINE, A(1), .. A(n)

The first option defines the events which will be used for computing results. Here, EVE_BEGIN and EVE_END are the beginning and ending event numbers for which the results will be computed, and EVE_INC is an event increment. The second option defines how the "Magnitude" is computed. You can have one, two or three A(i) and each on must be either X, Y, or Z. If you specify all three (the default) then the magnitudes will be the length of the vectors. Alternatively, the magnitude will be the length of the vector projected on two either a line (if one is specified) or a plane. For example

     -MAG_DEFINE X Y

will give you the length of the vector projected onto the X-Y plane.

The corresponding form of the REPORT command is:

     REPORT, NAME, -OPTIONS

where name must be either: LOCATION, MOTION, HEIGHT, GS, or REL_VELOCITY. The first of these reports the location, velocity, and acceleration of the points. The second reports the location of the points, their motion, the wave elevation at the points, and the clearance between the point and the sea, while the third reports only the height of the points above the waterplane. With a report name of GS, the dynamic "G" loads for the selected points are reported. Finally, the last report gives the wave elevation, the wave clearance, and the wave velocity minus the point velocity in global coordinates. If no report name is specified, all reports are produced. The only option available for reporting is:


     -EVENTS, EVE_BEGIN, EVE_END, EVE_INC

For certain situations, it is desirable to know the location, velocity and acceleration of one point relative to another point. The REL_MOTION command is provided for this, and instructs MOSES to compute the relative location, velocity and acceleration for a pair of points. The results are expressed in the body system of the first point. The form of this command is:


     REL_MOTION  PNT_NAME(1,1), PNT_NAME(2,1), ....  -OPTIONS

The options are:


     -EVENT, EVE_BEGIN, EVE_END, EVE_INC

     -MAG_DEFINE, A(1), .. A(n)

and they have the same meaning as they did for the POINTS command. The corresponding form of the REPORT command is:

     REPORT, -OPTIONS

The only option available for reporting is:


     -EVENTS, EVE_BEGIN, EVE_END, EVE_INC
