UEL visualization and strain energy for UEL

I am only seeing a "x" for a UEL at its first node. And I dont see any other node of UEL. Is it correct or some problem is there?
I also want to calculate the strain energy for whole model(including UEL). But in history output I am only seeing strain energy of Abaqus defined elements under "whole model strain energy". Can some one please help me in calculating strain energy of whole model including UELs
