Hi,
I am a BEng student and I am using OpenFoam 3.0.1 to study the movement of a free floating rigid body that is capsizing.

I would like to use the restraint sphericalAngularDamper with sixDoFRigidBodyMotion, so I studied the tutorial DTCHull and I added these lines in my dynamicMeshDict :

{
rotationDamper
{
sixDoFRigidBodyMotionRestraint sphericalAngularDamper;
coeff 11586;
}
}
}


However, the results are the same as the case without the rotationDamper.
I also tried to use other coefficients, but nothing has changed.

Moreover in my log.interDymFoam there aren't these lines that I find in the DTCHull case.

" Rotational constraint tensor (0 0 0 0 1 0 0 0 0)
....
Restraint rotationDamper: moment (-0 -0 -0) "

My feeling is that the input file is not properly read, but I cannot see what I am missing.
I would really appreciate some advice on this. Thanks in advance for any help.

Hi,
I resolved my problem.
In some lines of my dynamicMeshDict there were too many parentheses.
