How to create tank boundary transverse bulkhead and longitudinal bulklhead ? I had successfully creating the external panel for motion and mooring. But for stability analysis required compartment or tank definition.
Or any any way to model the hull and tank from other software and import to moses ?
Thanks,
Danial Asnawi
Hi Danial,
It looks like you are almost there. Are the panels you have in dark grey the boundaries? You need to add the "&describe compartment cname" before the "&describe piece" command. The order of the vertices for the panels is important. The normal should point outside for a compartment. If the order is backwards you can use the "REVERSE" command.
MOSES can also read Rhino .ply files if you have the compartments in that format.
I hope this helps.

Hi Georgina,
Could you explain how to import .ply from rhino for external panel for hull and compartment ? if you sample for this format please share.
We have a sample file that shows this. Please see your MOSES installation. The directory is /hdesk/runs/tests/convert. The files are ply.cif and ply.dat. The ply.dat file was originally from Rhino. Lines 00 and 01 were added to the top of the file. The last command, &fini, was added to the bottom of the file.
Let me know if there are other questions.
Is this correct definition for tank modelling based on panel as shown below ? and where should place the reverse for normal should point outside compartment.My current model generated same for external hull surfaces.

Hello Danial,
The format you show is correct.
I cannot comment on your use of the "reverse" command. You need to evaluate the normal for each panel. If the normal is pointing inside you should use "reverse yes" before the panel line and "reverse no" after the panel line.
