Standard Brick Element: Difference between revisions

Revision as of 22:35, 7 August 2012

This element is used to construct an eight-node brick element object, which uses a trilinear isoparametric formulation.

element stdBrick $eleTag $node1 $node2 $node3 $node4 $node5 $node6 $node7 $node8 $matTag <$b1 $b2 $b3>

$eleTag	unique element object tag
$node1 $node2 $node3 $node4 $node5 $node6 $node7 $node8	eight nodes defining element boundaries, input order is shown in the figure.
$matTag	tag of nDMaterial
'$b1 $b2 $b3	body forces in global x,y,z directions

NOTE:

The valid queries to a Quad element when creating an ElementRecorder object are 'forces', 'stresses,' ('strains' version > 2.2.0) and 'material $matNum matArg1 matArg2 ...' Where $matNum refers to the material object at the integration point corresponding to the node numbers in the isoparametric domain.
