    Hi,

    Is there anyone knows how to produce a table of hydrostatic Properties at a designated heel angle in Autohydro?

    Been looking high and low in the manual but there isn't any macro that enable this to be done :mad:

    Appreciate very much for any help towards solving this problem.

    Hi petlily,
    just don't define drafts and don't use /km parameter for ghs command. for example following commands will force to zero heel:
    ghs dr 1.1,1.15,...,2.8
    ghs /km
    So only use ghs command without any paramater. the result is a one-row hydrostatic table for defined draft, trim and heel angle.
    for multiple drafts write a macro and use a loop to calculate hydrostatic properties for different drafts. Then edit the results in word software to join the one-row tables to a perfect hydrostatic table.

    hope this help:)

    Hi babri,
    Thank you for your suggestion. Tried using the ghs but no matter how I tried, the heel is always forced to zero.
    The only solution I figured out, is to use hs instead of ghs, such as this;

    heel 5
    hs 1, 1.2, 1.4, ...3

    I still get the hydrostatic table at heel 5 deg albeit certain parameters have been omitted like KMt, KMl, etc. Note that the inclusion of new parameters such as BMt, BML, which is independent of centre of gravity.
