My simulation is to get an axial force connector at a modular floating structure.

1. How can the hydrodynamic pressure from ansys aqwa diffraction result link into ansys static?

I get this error in ansys static.

2. What does full Hydronamic Diffraction analysis mean?

3. I should get what result at ansys aqwa to link the result to ansys static applied hydradynamic pressure?

4. Does this pressure and motion result in anss aqwa enough requirements that can be linked to ansys static? If not what solution I should find in ansys aqwa diffraction to get a link in ansys static?

Hello,

You should have a link (pink line) between the Hydrodynamic Diffraction and Static Structural systems on the Project Schematic:

If this link already exists in your project, right-click on it to Delete, then drag-and-drop the Hydrodynamic Diffraction Solution cell on to the Static Structural Setup cell to create it again.

With the Mechanical editor closed, right-click on the Hydrodynamic Diffraction Solution cell and 'Update':

This will solve the Hydrodynamic Diffraction analysis, if required, and transfers the output files into the Static Structural solver files directory.

Double-click the Static Structural Setup cell to re-open Mechanical. Workbench may ask you if you want to re-read the upstream data, click Yes:

Once Mechanical has opened, the hydrodynamic files should be detected automatically by the Hydrodynamic Pressure object when you click on it.

If you solve the Hydrodynamic Diffraction analysis from inside the Aqwa Workbench editor (only), then the output files are not transferred to the Static Structural system. I guess this may be what has happened in your case.

I hope this helps.
