Why " *Node Print " prints information of only Constrained Nodes in Abaqus ?

Hello All,

I am Master student of Computational engineering at Ruhr University
Bochum, Germany. Presently I have to do testing and do post-processing of UEL Subrouitne for 9 NODE
Piezo-Electric Element .  I am not able to get the displacements of all  nodes in the
.dat file.  Below is my piece of code  of  INPUT file

*STEP,PERTURBATION
*STATIC
*NODE PRINT
U
RF
COORD
*endstep

"*Node Print " prints displacement of constrained nodes which is
ofcourse zero. Do you  know how do I get the output of all DOFs at all
nodes. Please find input file in attachment.

I would greatly appreciate any little help.

Thanks and Regards,
Somu
