Approved stability software

I use these guys:
http://www.wumtia.soton.ac.uk/software.html

Their stability program has been approved/accepted by UK and HKMD for many years.

 

Looks like an interesting program. I got all excited when their website said it had Mac support, but they lied... Thru virtualization only.

Siemens made a mac version of NX, but never shipped it. PC and linux versions work great, but its just another pain in the *** to have to support this microsoft garbage. :: shakes fist ::

If I ever got a pile of money, I'd take my software skills, and my other skills hire some people and make a modern general engineering software with some of the same super cool features only available in the 3D effects and motion graphics business. Make it all cross platform. It'd be awesome and not suck, I'd be able to farm out processes to remote hosts, update node based features procedurally instead of history based etc... :: shakes fist and curses sky again ::

But not that often as it requires a bit more data..ie a full on design rather than a quick check.

 

Paramarine looks good.

Alas, boatdesign is a hobby for me right now. NX is the breadwinner for me, it has what appears to be some really good shipbuilding tools, but I just haven't got the time to get my hands around them yet. Most of the tools seem geared towards very large ships, modular fabrication, and other things I don't have the requisite knowledge for yet.

There isn't much you can't do with NX, Nastran and Ansys. But 99.9% of that is overkill I think for a 18m catamaran. That and I am VERY early in the design spiral. My plan is somewhat like Inquisitor's. I am going to start with a smaller beach/camping/daysailing type cat and go from there.

 

As I know Paramarine has Parasolid kernel. It is interesting your opinion on Paramarine stability module.
