Hi guys, I'm design a fishing vessel (23m) and I would like to perform some optimization on its bolbous bow. Currently I'm using Rhino to model it, but I found it hard to do some variations on bulb dimension. So, I would like to ask you guys if you have some advice on it, like some plug-in for...

Hi, I'm trying to make a smooth transition between hull and a simple bulb form that I have done by lofting some sections. But I cant do it, I ve tried all kinds of tools that I ve know, no luck so far. Any ideas?

Got it.

What is transverse section lofting?

I tried, I have all offsets but I cant surface in a good way. I mean, I use loft in Rhino with all offsets, do you guys have any recomendation on how create surface after having offsets?

Anyone? :(

Hi, for my project I'm looking for a CAD model (any format) of Series 60 model, cb=0.7, no bulb and no transom. This is for a school project which I have a experimental seakeeping results and I will try to modify the hull lines to improve in someway seakeeping performances. Thank you all

Hello, i have ansys 14 in my pc and I`m trying to compute some simulation through Aqwa. The problem is, doesnt matter how I create my model, Aqwa solver always stop unexpectedly. Two messages show up: Hydrostatic Solve aborted The AQWA Core Solver stopped unexpctadly. But, the other...

allright, thank you guys the problem is that maxsurf has a poor modeler tools compared to rhino...

Allright, hope you can help me :)

Sure, this is the link for both .3dm and .iges files. https://www.dropbox.com/sh/h7um27sdtqe5fvw/AADMxmNySiNV10vqpDmlOk7Ba?dl=0

Hi, currently I`m trying to import as Iges format some surfaces from rhino to maxsurf. But its says that maxsurf only supports max of 20 surfaces. Does anyone know how to import more than 20 surfaces. PS: Ive tried import from .3dm extension but it is even worst because maxsurf only supports...

It's what I'm trying to say. Now I know the conditions that I have to measure to calculate my froude's number. Because intuitively I know that the boat will make more waves if the velocity grows, but how measure it? At planing conditions is hard to have a answer for that. I conclusion, what...

As I said I know that parameter is lenght. But when use the others?

I'm familiar with froude's number. I'm just having problem of what parameters (lenght, beam, volume) I have to use in high speed hulls, are there any pappers with this information?

Hello guys I'm doing some research about froude number. And I'm with a doubt about Froude's number, wich parameter I use when I'm analyzing the froude's number of high seed boar, like launch or jet skis? I mean, I've heard that I've to use the beam of the boat, but I'm not sure about it. Could...

Has it a free acess? I mean, Can I have acess to all of those documents? Because I heard that this towing tank business is quite of secret and they don't like that other people build another towing tank because they see it as a business competition.

MikeJohns said that you are designing one ... Do you have some contact? because I didn't find any in your public profile. I would apreciate.

Thanks guys. I'm just a studient yet, and at the moment I'm doing a research to try to find the better size for launchs and similar froude numbers. Do you guys have some literature which could help me?

Hello, it's my first post here. I'am doing a research at college, and I need to find some companies which offer the service of design towing tank. My college want to buy one because it doesn't have the technology for desing one. Does anybody knows a companie who offer this service facilitie...
