It seems a 6dof UDF containing vehicle characteristics such as mass and moments of inertia can be used for specifying a boundary as reprentative of ocean vehicle. It is required to have hydrodynamic loads on every part of the vehicle though. Although, definition of each part is possible individually, definition of differnt boundaries in dynamic mesh as a unique body seems not acceptable by the solver. Does anyone face similar issue? I appreciate any help.
Hi.
Yes it is possible.
Firstly you must have defined each part as an individual wall face.
Then use "Monitors>>Force/Moment" and select "Per zone" and"write" options to write down the force of each part individually on each iteration or time step.

Thanks a lot. As I mentioned in the question, This is possible and straight to report loads by defining the faces, but in the case of 6DOF analyses defining different faces for a single body make it impossible to use all of them as representative of the body in dynamic mesh menu. Thus, here is my question that how can we deal with such situation?!
I am afraid if this question has some issue in foundation, because if one wants to do so how is she going to manage mass COG and gyration radius?!
