get rotation of elements

[vehy]

Hi everybody
Is there any thing like nodeDisp to get rotation of elements nods.
I want to save rotation of elements in the variable, How can I do it?

try drift control between end nods!

I mean rotation in the end of the nonlinearbeamcolumn element.

recorder Node <-file $fileName> <-xml $fileName> <-binary $fileName> <-tcp $inetAddress $port> <-precision $nSD> <-timeSeries $tsTag> <-time> <-dT $deltaT> <-node $node1 $node2 ...> <-nodeRange $startNode $endNode> <-region $regionTag> -dof ($dof1 $dof2 ...) $respType
in $dof definition type 3, which gives you the rotation of node you want in each step of your analysis

I don't want to record it in file. I want to save it in the variable
