This data record specifies that 2nd order drift forces are not to be calculated for the current spectrum. It is applicable to any program except Aqwa-Naut.

(1) NODR specifies that the 2nd order drift forces are not to be calculated for the spectrum being defined. If more than one spectrum is input then a NODR data record is required for every spectrum for which drift forces are to be omitted.

(2) Where a User Defined Spread Seas Spectra is defined, this item specifies a direction for which 2nd order drift forces are to be omitted. For all other spectrum types this data is not required.
