Dear all,

currently I am studying the movement of the 3D object in water by using pimpleDyMFoam.

In DynamicMeshDict, I have to set up the parameter orientation.
like this,,,

sixDoFRigidBodyMotionCoeffs
{
patches ( Body );
innerDistance 25;
outerDistance 275;
centreOfMass ( 16.81 -1087.4 -1063.3 );
mass 4.1453e+06;

orientation
(
0.9953705935 0.09611129781 0
-0.09611129781 0.9953705935 0
0 0 1
);

I read openfoam wiki but I could not understand.
Can I calculate the angle of attack or rolling etc by using this orientation?
Does it affect the simulation?

what does "orientation" mean?

Thank you in advance.

Dear Shota,

I meet the same problem as yours.

The parameter definition for sixDoFRigidBodyMotionCoeffs in OpenFoam WiKi is out of date.

Maybe we have to read the corresponding code in order to figure this out.

Best,
