3.1.9. Element Command

This command is used to construct an element and add it to the Domain.

element $eleType $tag (num $nodes) $arg1 ...

Argument	Type	Description
$eleType	string	element type
$eleTag	integer	unique element tag.
$nodes	list integer	a list of element nodes with number dependent on ele type
$eleArgs	list	a list of element arguments with number dependent on ele type

Note

The type of element created and the additional arguments required depends on the $eleType provided.

The valid queries to any element when creating an ElementRecorder are documented in the NOTES section for each element.
