Hello,

To include your additional stiffness in Hydrodynamic Response calculations, you should define a Connection Stiffness matrix with the appropriate values. Then you need to turn on Beta Options: close the Aqwa Workbench editor, from the main Workbench page navigate to Tools > Options > Appearance, and check the Beta Options checkbox (near the bottom of these settings). Re-open the Aqwa Workbench editor, and you should find an option 'Include Linear Connection Stiffness Matrices' at the bottom of 'Common Analysis Options' in the Hydrodynamic Response Analysis Settings.

I hope this helps.

Mike
