Hello Everyone,

I am currently working on simulating the hydrodynamic response of a thin rectangular cuboid placed on water. While I understand that AQWA requires the mass and inertial properties of the surface body to simulate its dynamic response with a rigid body assumption, but I am curious to know if it's possible to simulate a hydroelastic response.

By hydroelastic response, I mean determining the hydrodynamic response of a flexible structure placed on water using Ansys AQWA. I would greatly appreciate it if anyone has insights into whether there are methods available within the Ansys package to predict the response of flexible structures placed on water.

Thank you in advance for any assistance or suggestions you can provide!

Hello, 

it depends on what your end goal application is but you could also look into coupling Aqwa with Rigid Body Dynamic application if this is relevant to you.

Alternatively, you can break down your cube into smaller shunks which are linked with connections where you can specify  its stiffness and damping coefficients.

I hope this helps,

Ingrid

Hi Ingrid,

Thank you for your quick response. Bascially, my end goal is to get the RAO of my flexible cuboid when its placed on water. I did think about the second option you mentioned which is to break my cuboid into smaller chunks and then interconnect them via connections by specifying the stiffness and the damping coefficients. But, in this case, I was wondering if I could estimate the individual responses of each of the chunks? or does it give the response of the entire structure? Please let me know.

Thank you!
