Reply To: Best way to apply a remote force and displacement to reduce DOFs

[mohan.urs]

Hey,

Applying a displacement directly to the faces with only the X DOF free would constrain the faces to move only in the X direction, without any rotation. This method directly restricts the movement of the nodes on the face to the specified DOF.

On the other hand, using a remote displacement involves defining a remote point and applying the displacement to this point. Remote points are particularly useful when you want to apply a displacement to the center of a face while allowing rotational freedom, or when you want to apply a force at a location away from the mesh without over-constraining the system.

In your case, since you want to eliminate rotation completely, applying a displacement directly to the faces with only the X DOF free might be the more straightforward approach. This would ensure that the faces are constrained to translate only in the X direction without any rotation.

If you need more insights on this, I would suggest that you explain the setup and your end goal with some snipshots.
