Ansys Aqwa - Sphere Modeling
 

Hello guys,

Well I just want a confirmation.

I am studying a submerged sphere using Ansys Aqwa. In the hydrodynamic diffraction-radiation analysis, I insert a spherical geometry. Ansys Aqwa is a Potential flow theory based software. As a result it doesn't calculate any viscous loads on the submerged body. All the calculated forces are perpendicular in the surface of the sphere and should pass from through the center of mass(The mass is distributed uniformly in the body). So, only for the 3D sphere, Ansys Aqwa can not provide any hydrodynamic moments for pitch, roll and yaw motions, right? Does anybody disagrees with this statement? Thank you very much!!
