These data records may be used to input an added mass (FIAM) or linear damping (FIDP) matrix in addition to the radiation added mass and damping calculated by Aqwa-Line or input via data records.

If two FIAM/FIDP entries are used in the same run or in successive runs (for example, Aqwa-Line followed by Aqwa-Drift), the second entry will overwrite the first.

As these are frequency independent parameters, the values defined in the FIAM and FIDP data records will apply to all the frequencies. Therefore there is no preceding FREQ/PERD/HRTZ data record for FIAM and FIDP.

(1) This data record keyword indicates whether the values refer to the added mass (FIAM) or damping (FIDP)

(2) This number indicates the row of the added mass/damping matrix to which the values in columns 21-80 correspond.

(3)-(8) These are the values which add to those in the existing added mass/ damping matrix or add to any subsequent added mass/damping values input or calculated by Aqwa-Line.
