    Hi, I m using Autohydro and I have model my our ship and add all tanks and compartments into hull. Then, i want to calculate intact stability for ship. But i did not write command (ghs). firstly ı want to calculate hydrostatics and cross curve. then i must calculate RA. can anyone help me?
    Thank you

    Dear Experts.

    I also facing problem in autohydro stability, i am new.

    Anyone have autohydro runfile for tank characteristic as per the picture attached and can show the graph.

    Thanks

    @MD Yusuf , what relationship do you seek between the stability studies and the forepeak sounding table? What do you want to get from the displayed graph to use in your stability calculations?

    Sorry, I can't help you with Autohydro. I thought that the sounding table and curves in your picture had been generated by you and that you needed to incorporate them into your stability studies. In any case, a tank can be treated in the same way as the hull hydrostatics of the ship, defining the "hull" of the tank and calculating its hydrostatics.

    Try using the command TC (it works with GHS and, usually, AutoHydro and GHS are compatible). The general form of the command is as follows:

    tc (name_of_tank) SO:.05 .1 ... 20 /STOP:FULL /VOL /WEIGHT /NOREF /NOLOAD /FSM
