Interface & Language Questions


Q: How can I plot multiple spectra on a single plot?
REV 7.05

A: You simply store the values of each spectra and then use &BUILDG to combine them. Click here for an example that does what you ask.


Q: In looking through Ultramarine supplied macros I came across the command: &M_ACT X.XXX NULL. What does this do?
REV 7.00

A: This specifies that the menus for which "XXXXX" will be valid are those in which "NULL" is a valid command. In addition, MOSES has no valid commands when "reading a model", and all macros are valid during this phase. Now, since "NULL" is never a valid command, the above says that "XXXXX" is valid only when reading a model. Click here to learn more about macros.


Q: Why I am getting the message "*** ERROR: XXX is not a valid option for this command"?
REV 7.00

A: This can result from many different sources, but here it is because you wanted to continue the input record but did it incorrectly. The continuation character \ must be the last thing on the input line. In your case you followed it with a tab character or two.


Q: After I changed the font with the preferences menu, my log file looked bad. Why did the columns not line up?
REV 7.00

A: You chose a proportional font. For the log to look good, you should select a fix pitch font.


Q: I expected the red crosses on graphics tabs to let me close those tabs but they did not. What do they do?
REV 7.00

A: They do close the tab, but you must be focused on a tab to delete it.


Q: When starting up a job displays initializing and command line is blank but why not display a dialogue box with wait/progress bar or something animated to give the user a better clue to when he can begin?
REV 7.00

A: There is a box in the lower right hand corner which displays Ready when you can input a command, and Busy when you cannot.


Q: What is a .ppo file?
REV 6.02

A: The .ppo file name stands for Post Processing Output, and is a general purpose file for data that MOSES can emit, that than can be used later by a separate MOSES run, or as input to other software. Here are some examples of the type of data that can be stored in a .ppo file, and the associated MOSES command to place the data in the file:

Panel Pressures fr_panp
Structural Loads File exp_aload
Structural Results beam, plate, joint
Normally, data is stored in the .ppo file, the file may or may not be renamed, and then used as input for another MOSES run. For instance, you could use the &surface menu commands to build a model of a semisubmersible, emit the model to the .ppo file, and then use this file as input to a MOSES run that computes the vessel RAOs. Click Here for information concerning the root file concept.


Q: Why can I run MOSES but a person in a different building cannot?
REV 6.02

A: Click here and read the discussion.


Q: How can I print the Moses manual?
REV 6.01

A: The following two links A4 size and US Letter Size should open acrobat reader and you can print from there.


Q: When we define text styles in MOSES, the changes show up in the graphs in the MOSES window but don't have any effect on gdv files. Why not?
REV 6.01

A: Text in graphics is treated differently for different formats. Most formats use drawn fonts. So that text can be properly rotated. For these formats, you will not see a difference. If you use postscript for gdv you will see a difference.


Q: How can I plot the joint and member checks ratios of selected range and at the same time show all of the plots?
REV 5.08

A: Try the following:

&PICTURE STARB -PLANE NOD1 NOD2 NOD3 -RATIO 0.85 999 -COLOR SELECT \
-ANO RATIO
Click here to see more options for the &PICTURE command.


Q: Is Ultramarine's software approved by the American Bureau of shipping?
REV 5.07

A: Coast Guard and DNV do not approve software. They approve calculations and designs that use a variety of software, but not the software itself. The only organization we are aware of that does this is the Norwegian Maritime Directorate, MD, and they approve mooring and stability only. We do know that our software has been used on numerous projects throughout the years, with the designs and calculations approved by various certification authorities. If you have a specific need for software approved by ABS, please let us know.


Q: Could you add a command, &BOOK for example, that would allow us to write some text that would appear on the first page of the output files?
REV 5.06

A: There are actually two ways to accomplish most of what you want in MOSES. The first is to, in the com file put

&device -OECHO yes
INMODEL
and then in the .dat file put
&type this is what I want to say
&type this too,
&device -OECHO no
which will put everything you type in both the log and the output file. The other is with &report. It works as
&report head -option
command
.
.
end
This internal menu is for writing a "report": head is the heading at the top of the page and option can be either -hard or -both. With -both what you report will be sent to both the output file and the terminal (and log), with -hard only to the output and with neither, it goes to the terminal. The commands you can use are: type, CUTYPE, or STYPE, and these act exactly like the similar command with an &.
