    in a word, no.

    What is it you wish to simulate?

    You are referring to squat.

    There was a very good technical paper/article in The Naval Architect about 1 year ago on this very subject.

    Software like maxsurf wont help you.

    Maxsurf won't help you at all.
    Look into RAPID (from MARIN) or ShipFlow.

    Or, if you have lots of time and computer power, try OpenFOAM, Fluent or some other CFD code.

    There are also many empirical and semi-empirical methods.
    For a start look at:
    http://www.ship-squat.com/what_is_ship_squat.htm
    http://shipsbusiness.com/squat-factors.html
    There are several papers on the net that compare the various methods.

    Tim Gourlay's PhD thesis and subsequent publications might also be useful:
