Defining relative displacement on ABAQUS (as opposed to absolute displacement)
Defining relative displacement on ABAQUS (as opposed to absolute displacement)
(OP)
I have a body on ABAQUS that translates and rotates a bit. I want to create an object that is NOT connected to the main body but displaces relative to that body. Is there any way to apply a relative displacement in ABAQUS, as opposed to the conventional absolute displacement boundary condition?
I would really like to be able to simply define the relative displacement of this object relative to the main body.
I'm open to any suggestions
Thanks!

RE: Defining relative displacement on ABAQUS (as opposed to absolute displacement)
1. Can you attach a coordinate system to a node on your reference and apply the displacement using that coordinate system? What I am not sure about is whether the coord sys will move with a particular node or if it will stay fixed.
2. I am sure you could do this with a user defined subroutine (probably DISP). But that would surely be painful.
