    Hello Victor, I have sent you a mail with the model of the hull. I have a Freeship+, the latest version.
    Thank you very much, you have done a great job with this program! :)

    The problem is in your model - two layers are empty.
    Click Layer-"Delete empty" and Delft calcs is Ok.

    I have deleted the unused layers but it keeps giving me the error.
    And it seems that the error doesn't depend on the model, because I have opened the Freeship! demo7.fbm and tried to make the same calculation.
    Now watch this:
    - the first time I start the Delft module it works ok. I tell him the speed range and i check the "Extract data from current hull" box. It works, and the graph appears.
    - then I exit the Delft module
    - then I try to start the Delft again (I want to repeat the calculation) and it gives me the "access violation" error!
    I have to exit Freeship+ and start it again to use the Delft again, and I can use it only once.
    I have tried the same thing with demo8.fbm and the same thing happens.

    The strange thing is that with my hull it gives me the error even for the first module start. With demo hulls the Delft module works, but only once.

    P.S.
    I would like to hear from other users if they have the same problem with Delft resistance module. Maybe it is something about my PC...

    Daiquiri,

    Rest assured, it has nothing to do with your (or any other) model. Whenever you see the "access violation" error message it means that the program is trying to access memory allocated to another program or process. In other words Freeship is trying use memory that is not belonging the freeship. This is a program error that can easily be fixed by the developer doing some basic debugging.

    I have exported my model as FEF file and imported it again. When I import the FEF model I can execute Delft module, but only once. The error appears again when I try to repeat the Delft calculation. :(

    I will continue this in private, if you prefer.

    Hi, Im a student in Engineering and I am tasked to identify the motion of boat when interacting with waves. Im using Free!Ship to export files which then can be inputted into PDstrip to obtain the transfer function values and variables to solve for MSI. Can anyone give me some pointers or directions on how I go about doing this? Any help will be greatly appreciated, thanks.

    my email: turbotommyp@hotmail.com

    There is a way to export a maxsurf file to freeship.
    It is; export iges from maxsurf and import in into Rhino. From Rhino you can export a VRML file, and VRML files can be read by freeship.

    Can hydrolink export VRML?
