A simply question
is added mass used by Ansys Fluuent in 6DOF model differential equations

Displacement of floating structure has to be measured that is product of vortex induced motions. The unit has 3 degrees of freedom sway surge and yaw.
Model of turbulence is k-omega SST.
So the question is does the calculation include added mass or not

Please take a look at this thesis. The answer is yes, because the added mas is a consequense of solving the equation of motion of a body inmersed in a fluid and that is what the 6DOF model does. But you have to calculate the added mass through a propper method, I mean the model 6DOF solves the equation of motion of the body but if you want to know the added mass you have to calculate this. I hope this helps you. Regards. Gonzalo
