Currently, I'm working on creating a hexagonal Single Point Mooring model in MOSES EDITOR. I need to form the compartment model inside the SPM.
Since the SPM has a hexagonal form, thus the compartment has to be a Triangular Prismatic as you can see in the attached figure below. I found it difficult to create the triangularly prismatic form if I use plane command.
Is there any alternative method that can be used for this work?
Thank you in advance.
Here's the example of my build up command:
&dimen -save -dimen Meters M-Tons&describe body COBAPRISMA&describe Body Tank001pgen -PERM -1 -PORT -LOC 0.00 0.00 0.00 -diftype NONE plane 0 -cart 0.00 0.00 3.474 0.00 3.474 5.641 plane 6.0040 -cart 0.00 0.00 0.000 0.00 0.000 5.641end pgen&describe Body Tank002 pgen -Perm -1 -LOC 0.00 -3.474 0.00 -diftype NONE PLANE 0 -cart 0.00 0.00 0.000 0.00 0.000 5.641 plane 6.004 -cart 0.00 0.00 3.474 0.00 3.474 5.641end_pgen
I attached a wedge.zip. This is a set of file that show how to make a wedge or triangle shape compartment. Please run spar.cif before running c_spar.cif.
Please review and let us know your questions.
Your code worked really well, thank you.
Yet, I do have another question,
While I am using the 'difference' command to make a hole inside of the body, why cannot I generate the hydrodynamics command in order to obtain the RAO? Is it because of the 'difference' command not generate the closed surface?
Thanks in advance.
here I attached my built-up command
Please add the line
&describe piece Pname -ditype 3ddif -cs_curr 1 1 1 -cs_wind 1 1 1
before the panel definitions. In the above command "pname" is the piece name.
Also the command "INMODEL" does not need the body name after it. The command is simply "INMODEL".
I hope this helps. Please let us know of other questions.
Dear Georgina, thanks for helping me!
However, if you don't mind, I would like to ask another question,
After the hydrodynamic analysis was generated (I was using 3ddifraction theory), why is it so difficult to find the equilibrium of single point mooring (calm buoy) for mooring analysis during the time domain simulation?
