6.15.4. MSMX and MSMY Data Records—X and Y Symmetry

These data records may be used when the moonpool is symmetrical about the X or Y axis of the global reference axes (GRA) in the position defined by the element topology in this data category and the node coordinates input in Data Category 1.

Note:  Elements on half or quadrant of moonpool surfaces are required to be input when one or both data records are defined. However, the symmetry of a moonpool will be aligned with the symmetric configuration of the associated structure. For example, if the associated structure's corresponding port-starboard and/or fore-aft symmetry are not activated, Aqwa will generate new moonpool elements by mirroring those already defined.
