Orientation of Part (MOSES)

Hi,

I would like to ask regarding how the orientation in MOSES works, and what is the difference between using the following

Method 1:

"in dat file"


$ ---------- INSERT BARGE DATA ------------
&DESCRIBE BODY %VNAME
&INSERT barge.dat

$ ---------- INSERT CARGO DATA ------------
&DESCRIBE part %CARGO% -move 82.79 0 %vdepth%+3.295 0 0 90
&INSERT CPP_JKT.DAT

and

Method 2:

"in "CPP_JKT.dat" converted jacket data

&describe body jacket cpp_jkt -move 82.79 0 %vdepth%+3.295 0 0 90

and 

Method 3:

"in ".cif " file

INMODEL

MEDIT

$
&DESCRIBE body cpp_jkt
&INSTATE -MOVE cpp_jkt -move 82.79 0 %vdepth%+3.295 0 0 90

END_MEDIT

My question is which of this method is correct for reorientation of cargo on top barge deck. I found that the part did not move using method 3 and 2. Appreciate for some clarification on how MOSES reposition "part" or "body"

  • I suspect this is a transportation analysis. In such analyses everything belongs to one body, i.e. the barge, while the jacket is a part.

    The &DESCRIBE PART can be issued either before you read the jacket model with &INSERT, or from within the .dat file that contains the jacket description as done in Method 1.

    The jacket will not move in Method 2 because the jacket will always be a part in the analysis and not a body. I see you are using &DESCRIBE BODY jacket -move in Method 2; this is wrong. I always use &DESCRIBE PART %cargo% -move to position the cargo onboard as you are doing in Method 1.

    Finally, in Method 3 you are issuing &DESCRIBE BODY for the jacket again; not good. &INSTATE is not be used for positioning cargo, but bodies in the analysis; i.e. the barge. This is mentioned in the Reference Manual, page 134. You need to read the manual first.
