  The ship I am going to study it has a special cabin, when I do the RAO analysis of the ship, the ship appears to have multiple intrinsic cycles in longitudinal rocking, some of which have negative values of additional damping coefficients, and some of which have exceptionally large values of additional damping coefficients, so how do I solve it.
