Currently i'm working on issues related to high-speed craft design; I'm wondering how do Maxsurf modules like MaxSurf { modeler, stability, structure, motion, resistance, etc} handle errors(I don't only use Maxsurf modeler) , I mean is there a report or research about each modules error ranges in real world projects and in practice? any help or suggestions would be appreciated;
btw thanks in advance;
Yes it is ok, but you can also use the Rinoceros program (Rino3d), TRIBON, NAPA or the Delft ship Software.
Dear Ehsan,
It depends on the hull form you want to design. If you want to design a prismatic planing cart, it is expected that the software well predict the hydrodynamic characteristics and lead you to design a hull with optimized resistance and trim angle. But for realistic hulls not being prismatic anymore, I don think that the software has good accuracy. For this case, you should use numerical methods, or your own Mathematical model.
Good Luck
Is great, no miss on that one, also you can have a look at:
Seapower sea-power.net
Wolfson unit resistance program
and if you look in prosurf website they have a program for resistance and powering for high speed crafts
good luck
All softwares have inherent errors specially on resistance and hydrodynamical calculations. Tank test will give you the most reliable data, without any doubt.
MaxSurf uses imperical formula for predicting the resistance/ propulsion characteristics of a model. If you follow the traditional shape- you'll get a better result (Not accurate) But, if your research is about a hull form, you will not. You have to go for CFD or towing tank for that.
Maxsurf software is very good, but my advise for resistance the program is simply estimate the resistance and not so accurate. It better to use CFD for the resistance analysis.
