20.4. The REA* Data Record - Initial Articulation Reactions

* denotes articulation number (see (1) below)

See Starting Conditions Definition - STRT (Data Category 15) for a discussion of the interaction between the RDEP option and the POS* and REA* data records.

(1) The data record keyword indicates the corresponding articulation number for the positions in columns 21-80; for example, enter REA1 for Articulation 1, REA2 for Articulation 2, .... RE10 for Articulation 10.

(2)-(3) This is to indicate which spectrum and mooring configuration the reaction is defined for, only needed for multiple spectra/mooring configuration cases. If omitted the same initial reactions will be used for all spectra and /mooring configurations.

(4)-(9) These are the initial reactions applied by the articulation to the 1st structure on the relevant DCON data record (The DCON Data Record - Define Constraint Position) in Data Category 12. The reactions are three forces and three moments. The reactions are applied in the global axis system. The LAAR (Administration and Calculation Options for the Aqwa Suite) and LSAR (Administration and Calculation Options for the Aqwa Suite) options, if used, apply only to output reactions.
