13.11. WCIC Data Record - Wave-Current Interaction Coefficient

This data record is used to specify the wave-current interaction coefficient for the mean drift force coefficient of a structure. Only one WCIC record may be defined per structure.

Note:  

  • If a WCIC record is defined for a non-diffracting structure, it will be ignored.

  • The coefficient must be within the range [0.2, 0.4] (G=9.81). To take account of different unit systems, the Aqwa solver multiplies the default translation values by 9.81/G only, where G is the value of gravity input in Data Category 5.
