16.6. The FDOF Data Record - Deactivate Freedom at the Structure Center of Gravity

Aqwa allows any combination of the degrees of freedom of a structure to be deactivated. It is preferable to use this data record to replace the DACF data records if they exist.

A maximum of 99 articulations defined by both the FDOF and DCON data records is allowed.

(2) – (7) Indicators of the deactivated degrees of freedom (three translational and three rotational, each represented individually).

If '1' is input, the degree of freedom is deactivated in the global axes.

If '0' is input or it is blank, the degree of freedom is not deactivated.


Note:  This data record is ignored if no degrees of freedom have been deactivated. Only one valid FDOF data record is allowed for a structure.
