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
