six degrees of Freedom.. NEED HELP!
 
Hello everyone!
i'm having several problems managing the new sixDOF in OF1.7..
I can't figure out how to block or use any type of constraint on the floating object in the tutorial.

here is my pointDisplacement file:


object pointDisplacement;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 1 0 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
stationaryWalls
{
type fixedValue;
value uniform (0 0 0);
}
atmosphere
{
type fixedValue;
value uniform (0 0 0);
}
floatingObject
{
type sixDoFRigidBodyDisplacement;
centreOfMass (0.5 0.5 0.5);
momentOfInertia (0.08622222 0.08622222 0.144);
mass 9.6;
rhoInf 1;
report on;
value uniform (0 0 0);
constraints fixedPoint (0.5 0.5 0.5); // here is the problem!!

}
}


I really can't understand which is the correct syntax...

can anyone help???

thanks a lot!
