I am doing hydrodynamic research in AQWA of NAULILUS-10 semi-submersible floating platform. The geometry model is created in DM. When I sew or unsew all the downwater surfaces as a integrative surface, the hydrodynamic data e.g., RAO, added mass, radiation damping and hydrostatic stiffness will change l lot. 

So should the surface of platform be sewed together?

Hope you reply! Thanks.

Hi, whether the whole structure surface is split into several surfaces or not, as long as all the surfaces of a structure are put into the same component in DM, then it should be okay. Besides, you need to ensure the normal directions of the surfaces are all pointing toward the fluid region. 

BTW, the DM is going to retire, we'd recommend our users use Discovery and SpaceClaim for more capabilities.

Hi, thanks for replying. Could you please tell me how to check the normal direction of the surfaces? In AQWA or in DM? 

By the way, I used to creat my model in SpaceClaim, but I think it is not so comvenient like the DM in modeling complicated structure beacause it need to transfer the solid to surface for AQWA and is hard to parameterization.

Thank you again!
