Node Envelope Recorder

The EnvelopeNode recorder type records the min, max and absolute max of a number of nodal response quantaties. The command to create a node envelope recorder is:

recorder EnvelopeNode <-file $fileName> <-xml $fileName> <-time> <-timeSeries $tsTag> <-node $node1 $node2 ...> <-nodeRange $startNode $endNode> <-region $regionTag> -dof ($dof1 $dof2 ...) $respType'

---

$fileName	name of file to which output is sent. file output is either in xml format (-xml option), textual (-file option) or binary (-binary option)
-time	(optional using this option places domain time in first entry of each data line, default is to have time ommitted)
$tsTag	the tag of a previously constructed TimeSeries, results from node at each time step are added to load factor from series
$node1 $node2 ..	tags of nodes whose response is being recorded (optional, default: omitted)
$startNode $endNode ..	tag for start and end nodes whose response is being recorded (optional, default: omitted)
$regionTag	a region tag; to specify all nodes in the previously defined region. (optional)
$dof1 dof2 ...	the specified dof at the nodes whose response is requested.
$respType	a string indicating response required. Response types are given in table below.

disp	displacement*
vel	velocity*
accel	acceleration*
incrDisp	incremental displacement
"eigen i"	eigenvector for mode i
reaction	nodal reaction

EXAMPLE

recorder EnvelopeNode -file nodes.out -time -node 1 2 3 4 -dof 1 2 disp
