    The sourceforge website, unlike this forum, is a platform especially created for the development and distribution of open source software. It also has features such as a forum, bug tracker, website, version control and much more. So this would mean that all these features could be accessed in one single place and on a permanent basis.

    Apart from the fact that these features are not available at boatdesign.net I doubt it was ever the intention to distribute software in a forum such as this one.

    But it's up to Victor.

    We don't need all of those capabilities here. And the original intentions of a forum started many years ago are not necessarily valid now.

    Leo.

    You don't. But maybe Victor does, so it's really up to him to decide.

    Ok. But what happens if I get the latest version, zip it, and post it here? Victor gets to keep control over developments, just as before.

    Sure.
    I'm not trying to keep you from posting anything here, although it would be more polite to leave that to Victor in my opinion.
    I'm merely offering Victor my admin rights over the FREE!ship project at sourceforge.net so he has a good, trusted and free platform to release his software.
    It does not exclude you, him or anyone else to use this forum in the way it has always been used.

    Sorry for asking, but why is this such an issue?

    If he wants to, he can. I might be labouring under a misapprehesion, but I thought the code was able to be freely distributed.

    And a splendid gesture it is. It's just excruciatingly slow.

    I just proposed it as a quick solution to something people have been piddling around with for many months.

    There's no rancour intended and I have no vested interest. (I don't use it myself).

    This is the full version (3.10) of the freeship. If you dont have the full version, then unzip all the files into a folder, then replace the old files with the ones present in the 3.12 version. Now you will have the complete 3.12+ version.

    Now I understand.
    Victor simply hasn't shown any interest in it. He might still not be interested now, but since there seems to be a demand for a more reliable download site he might want to consider moving to the sourceforge site. He can use the old freeship account or start start a completely new one, or leave things just as they are.
    We'll see.

    I think that this is a great place to put some useful free codes for students and those from under-developed countries (like New Zealand).

    I'm putting together the next demo of Flotilla which will include Surface Effect Ships and hovercraft and I hope to post it on this forum. It will be crippled in some ways, but it will certainly be useful for some exercises and as a way to extend the work in textbooks like Faltinsen's "Hydrodynamics of High-Speed Marine Vehicles" and online notes such as Chris McKesson's "The Practical Design of Advanced Marine Vehicles".

    If I have time I'll try to make the next demo output a Delftship table of offsets for displacement hulls for your comments. I'm sure we can eventually make Michlet and Flotilla click with Delftship.

    That is a very generous thing, Leo. You have my respect. (But I still hope you'll make some money too with your software :) )
    I hope that grateful people from New Zealand will return back by gifting you at least few flocks of sheep. :p

    Only generous to a point, Slavi.

    As I said, the demo will be enough to do some instructive hydrodynamic examples and to conduct some parametric studies, but not much more. I'm now trying to collect as much experimental data as I can to go with the programs so users can compare predictions with those of other codes. That IMO is the best way to illustrate the limitations of thin-ship theory. And the reliability or otherwise of experiments :)

    Cheers,
    Leo.
