Hi all.. I a trying to learn MOSES the hard way, from the reference manuals, online tutorials and looking at the files from vessel library. I am creating the model of a semisubmersible of arbitrary dimensions, for hydrodynamic analysis. I have reached this stage after few trial and error. I have been writing commands in the command line. I have also given those steps below. I have tried a lot but, still not been able to figure out how to create DAT file and CIF file. Is there any command to save the current status of the model to a DAT file? Also, I have used the &SURFACE command till now. Should I define panels separately from here or create a mesh? I know these are lot of questions but, I am really stuck here. Any help or hint would be appreciated. Thanks.

Hi Vishnu,
I agree with Lars.
In your original post you provided a snapshot of your model. In the past the cross beams / bracing have not been part of the panel model. Other projects include the bracing as Morison beam elements. Not having to mesh bracing saves a large amount of time.
Another option is to use the MOSES Hull Modeler. MOSES now comes with a GUI modeler. Please see the MOSES Hull Modeler. It should have been installed when the MOSES solver was installed. I see you are nearly there with the &surface menu. Maybe next time for the Hull Modeler.

Thanks Georgina. I will definitely try the hull modeller. I believe it's similar to the Maxsurf modeller. The layout looks the same. Don't know if the method is different. Once I get these basic steps right, I will move on to your tutorials in the YouTube channel.
