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.

I got you. But to make it clear, I am only exaggerating the deformation 1000 times for the post-processing in the ADAMS view. I am not sure why exaggerating the flexible body deformation in post-processing is dealing with the modal flexible bodies theory. Yes, I agree the results are not changed when exaggerating since exaggerating is for a better animation which I am seeking too.

But I will look up the theory to see how scaling in post-processing is linked to the theory. Thanks for the directions.
