Hi all,

I want to constraint heave motion for a floating cylinder. From what i read about the 6 DOF Rigid Body Motion Constraint, fixedPlane seems ideal for me as i wish to analyse transverse and in-line motion.

However, I am unsure on how to set the conditions and could not find any tutorial using this constraint.

http://openfoamwiki.net/index.php/Ma...nConstraint.22

The above link suggests a reference point is required and the direction.

Could anyone guide me on how I may set this constraint?

Thank you.

Regards,
Prasad

I need help in specifying fixedPlane constraint in dynamicMeshDict for a 2D case in the x-y plane

Is this entry the correct way

fixedPlaneXY
{
sixDoFRigidBodyMotionConstraint fixedPlane;

fixedPlaneCoeffs
{
refPoint (0 0 0);
direction (0 0 1); //normal direction to plane
}
}
