Aahh..the beauty of a cut and paste SOR :D Ok, so based upon your numbers, she would have a Fn of 0.9..this is post hump speed. Not technically...
Do you have any dwgs you can share showing your - should be strong enough - new design?
Is your plan via a series of calculations to demonstrate the changes versus the existing method, as being valid and verifying your 'new' design?...
For ref: They are used extensively in the European pleasure boat market and now, becoming more popular with CTVs at windfarms in the North Sea....
Are all 3 elements noted above, the same element type?
Understand the elements and connectivity you use, when you select the elements to create the foil section. Clearly there is an incompatibility...
This suggests that you are using incompatible elements....or incorrectly defined elements.
Can you define what are the elements used in question at: 18882, 25371 and 27404
Not withstanding the cost issue issue, 2 x smaller units are the best way to go. Ostensibly for redundancy and better fuel economy too. As you...
There is no Munk Moment. You do not understand what a Munk Moment is.... A body needs to be fully immersed in a fluid for there to be a Munk...
This is not a Munk moment. The body needs to be fully immersed in a fluid for the Munk Moment., A yacht hull, is not!
It is not 'just' the material. But the detailing. Do you have an image or dwg showing how this connection is done. Since the devil, is in the...
That then suggests the way have modelled the bilge keel, or the analyse option using the model is creating the issue. Rather like using a model...
Do you mean..."best" or "compromise"..? Im now wholly sure either would be appropriate replacements. I just think such issues can be better...
To add to JEH's excellent summary. Once you read JEH's post you'll understand that there is no such thing as "optimal", other than in the minds...
Failure to converge can be for many reasons, but ostensibly, there is something that is modelled or selected that is not "closed". Like running an...
Could-a Should-a Would-a Speculation based upon zero info, serves no one.
A Munk moment only applies to a fully submerged body. A yacht hull, is not fully submerged!
That's probably because the term used in the question, is incorrect and misleading. When a vessel is stable, the KG (G) is below the metacentric...
Aahh...back in the day when we could have proper reasoned and unbiased debates with posters seeking answers.
