The Node recorder type records the response of a number of nodes at every converged step. The command to create a node recorder is:

recorder Node <-file $fileName> <-xml $fileName> <-binary $fileName> <-tcp $inetAddress $port> <-timeSeries $tsTag> <-time> <-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)
inetAddr	ip address, "xx.xx.xx.xx", of remote machine to which data is sent
$port	port on remote machine awaiting tcp
-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

RETURNS

>0 an integer tag that can be used as a handle on the recorder for the remove recorder commmand.

-1 recorder command failed if integer -1 returned.

NOTES

• Only one of -file, -xml, -binary, -tcp will be used. If multiple specified last option is used.
• -tcp option only available for version 2.2.1 and higher.
• In case you want to remove a recorder you need to know the tag for that recorder. Here is an example on how to get the tag of a recorder:

set tagRc [recorder Node -file nodesD.out -time -node 1 2 3 4 -dof 1 2 disp]

EXAMPLES

1. recorder Node -file nodesD.out -time -node 1 2 3 4 -dof 1 2 disp;

Generates output file nodesD.out that contains relative displacements in x and y direction at nodes 1, 2, 3, and 4. The output file will contain 9 columns (time, disp. in x at node 1, disp. in y at node 1, ... , disp. in y at node 4))

2. recorder Node -file nodesA.out -timeSeries 1 -time -node 1 2 3 4 -dof 1 accel;

Generetes output file nodesA.out that contains absolute accelerations (ground motion acceleration + relative acceleration) in x direction for nodes 1, 2, 3, and 4.
