I had to quit quickly last night before I could go over what I wrote. The problem is that for a given L and B, I is a fixed value - not...
I like your original formula the best. Most will recognize that LB^3/12 is the inertia of the rectangle and will assume that K is some factor...
From my statics book, I get the following rectangle: I = 1/12*L*B^3 (1/12 = 0.083333) For a diamond: I = 1/48*L*B^3 (1/48 =...
I did a test in ProSurf for a typical round bilge hull to test the error in the moment of inertia estimation. For the simple test hull, the...
That was partly my fault for not paying attention to the details. K = [Awp / (L*B)]^2 I = K*LB^3 / 12 ... Yes, there is a problem trying...
Hi Steve, Since these are empirical (not exact) equations that try to estimate the value of initial stability using a limited set of input...

I don't know SolidWorks99, so I can't really help there. However, try looking the the manual for words like "unwrap", "flatten", "layout", and...
Do you have the hull defined on the computer already - frames, surfaces, or some other definition? To be able to use a computer program to unwrap...
I have a number of customers that use CADKEY with our ProSurf program and like it very well. To do more sophisticated curve and surface work in...
Hello From New Wave Systems, Chris forgot to mention that he sells Rhino software, training, and support. He also forgot to mention that there...
The details of CFD for vessels are so complicated that I don't think it is advisable to try and understand much unless you spend some time with...

In response to Gades' post, From what I've been told, about the best repeatable accuracy that you can achieve in a towing tank is about 1/2 of...
I just looked at EXA Corp and its "Digital Physics" technology. It's hard to dig through the PR and hype, but I do like any solution that...
Hello Again, Not that I'm an expert either (and I even specialized in hydrodynamics for my master's degree!), but simplistically, there are...
Hello From New Wave Systems "What principles do you need to write a CFD?" If you have to ask, then you don't want to know the answer. Many...
Hello From New Wave Systems, I think we were the first to come out with a lower cost boat design program that was limited to fewer surfaces. I...
