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:

  1. The valid queries to a Brick 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.
  2. This element can only be defined in -ndm 3 -ndf 3
