Hello Foamers,

In OpenFOAM 4, there are some extra stuffs as explained in

http://openfoam.org/release/4-0/

Specifically, to my interest, it says,

Rigid Body Dynamics

• rigidBodyDynamics: new library for the dynamics of n-degrees of freedom (n-DoF) articulated bodies in parallel. » more »
• rigidBodyMeshMotion: new library for the mesh-motion of multiple articulated rigid-bodies with joints, restraints and external forces. » more »
• Vector algebra: redesigned to support spatial vector algebra. » more »
• Examples: the interDyMFoam tutorials, e.g. for marine engineering (DTCHull) are all updated to use the new rigid-body dynamics and mesh motion libraries. » more »

I am highly interested in external forces in rigidBodyMeshMotion.
Can anybody tell me how exploit this module, or, have anybody used it?

Actually, I want to add an external force to the vibrating body to make forced vibrations. Currently, I could make it just vibrate at its natural frequencies (I am using linearSpring).

Thanks for your help in advance!

Best,
Sachin
