Hi dear foamers,

When I try to use sixDoFRigidBodyDisplacement boundary in pointDisplacement for a flexible dropping wedge, the solids4Foam solver gives me the error:

"Unknown patchField type sixDoFRigidBodyDisplacement for patch type wall"

So I wonder if sixDoFRigidBodyDisplacement is available in solids4Foam + foam-extend 4.1.

If I use "solver velocityLaplacian" in dynamicMeshDict, I cannot set the mass, momentum ineria and others in pointMotionU.

So I have to use "solver displacementLaplacian" with pointDisplacment boundary file.

Anyone has any experiences?

Thanks,
Michael
