Hi Foamers,

I am trying to model multiple floating objects in OpenFOAM. I started my case by using the floatingObject tutorial and managed to get two objects floating in 2.2.0. However, there is a problem when I try to model the similar case in 2.3.0 as the settings for dynamic motion are slightly different.

My problem is that, in the dynamicMeshDict for 2.3.0:

dynamicFvMesh dynamicMotionSolverFvMesh;
motionSolverLibs ("libsixDoFRigidBodyMotion.so");
solver sixDoFRigidBodyMotion;

sixDoFRigidBodyMotionCoeffs
{
patches (object1);
..................
}

sixDoFRigidBodyMotionCoeffs
{
patches (object2);
..................
}

Writing 2 separate sixDoFRigidBodyMotionCoeffs, one for each of the objects in the same dynamicMeshDict does not seems to work, only one object is picked up for the dynamic motion. Even putting two of the patches together (one after another) under one sixDoFRigidBodyMotionCoeffs doesn't help either. Would be grateful if anyone know how to get two (or even more) objects to run under sixDoFRigidBodyMotion in 2.3.0 simultaneously.

Kind Regards,
tyoung
