The OpenSees recorder Command is used to define the analysis output.

The node recorder will be used to output the horizontal and vertical displacements at node 3 into a file named Node3.out:

recorder Node <-file $fileName> <-time> <-node ($node1 $node2 ...)> <-nodeRange $startNode $endNode> <-region $RegionTag> <-node all> -dof ($dof1 $dof2 ...) $respType

recorder Node -file Node3.out -time -node 3 -dof 1 2 disp

The element recorder will be used to output the element forces. Element forces for element 1 will be output into file Element1.out:

recorder Element <-file $fileName> <-time> <-ele ($ele1 $ele2 ...)> <-eleRange $startEle $endEle> <-region $regTag> <-ele all> ($arg1 $arg2 ...)

recorder Element -file Element1.out -time -ele 1 force
