How to find displacement history of a node in Adaptive Mesh.

Dear Experts

I could not monitor a displacement of a node when Adaptive mesh is employed because mesh is deleted and created continuously.

 Does anybody know how to observe displacement of a point of adaptive mesh ? 

 I am pulling hyper elastic rubber and investigate tip of rubber end displacement. 

Eventually I like to draw Load-displacement graph. 

Thank you.
