How to constraint 6DOF for a surface in a Flexible body (MNF)?

I have generated an MNF file in Abaqus and a node of a surface is fixed and the node is MPC beam constraint to the target surface. My FEA results are correct and the surface tied to the node is fixed as expected.

Now the MNF file with these BCs is generated and imported to Adams. Now I want to compare deformation from Adams and Abaqus. They are totally different even though the surface was fixed in ABAQUS and had zero displacements, it has displacement in ADAMS. Please look at the following image for more information and please help me out with what causes this issue.

Hi Abbas,

I am guessing this is only because where you define your zero point for the deformation output. Please try to set the datum node (you find it in the flexbody modify dbox) to the node id that is fixed to ground. Then this will be the zero point of the deformation coloring, in a similar way as it is for your FE case.
