Element

The Element recorder type records the response of a number of elements at every converged step. The response recorded is element-dependent and also depends on the arguments which are passed to the setResponse() element method.

The command to create an element recorder is:

Model.recorder(“Element”, destination)

`destination`	`str`
`precision`	`int`	number of significant digits (default is 6)(optional, default: records at every time step)
`time = False`	`bool`	using this option places domain time in first entry of each data line, default is to have time omitted
`closeOnWrite = False`	`bool`	using this option will instruct the recorder to invoke a close on the data handler after every timestep. If this is a file it will close the file on every step and then re-open it for the next step. Note, this greatly slows the execution time, but is useful if you need to monitor the data during the analysis.
`time_step`	`float`	time interval for recording. will record when next step is `deltaT` greater than last recorder step.

recorder Element 
    < -file $fileName > < -xml $fileName > < -binary $fileName > 
    < -precision $nSD > < -time > < -closeOnWrite > < -dT $deltaT > 
    < -ele ($ele1 $ele2 ...) > < -eleRange $startEle $endEle > 
    < -region $regTag > 
    $arg1 $arg2 ...

`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)
`nSD`	number of significant digits (optional, default is 6)
`-time`	(optional using this option places domain time in first entry of each data line, default is to have time ommitted)
`-closeOnWrite`	optional. using this option will instruct the recorder to invoke a close on the data handler after every timestep. If this is a file it will close the file on every step and then re-open it for the next step. Note, this greatly slows the execution time, but is useful if you need to monitor the data during the analysis.
`deltaT`	time interval for recording. will record when next step is `deltaT` greater than last recorder step. (optional, default: records at every time step)
`ele1` `ele2`…	tags of elements whose response is being recorded – selected elements in domain (optional, default: omitted)
`startEle` `endEle` ..	tag for start and end elements whose response is being recorded – range of selected elements in domain (optional, default: omitted)
`regTag`	previously-defined tag of region of elements whose response is being recorded – region of elements in domain (optional)
`arg1` `arg2` …	arguments which are passed to the setResponse() element method

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.

NOTE:

The setResponse() element method is dependent on the element type, and is described with the Element Command.
