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

element bbarBrick $eleTag $node1 $node2 $node3 $node4 $node5 $node6 $node7 $node8 $matTag


$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


NOTE:

  1. Note: Node numbering for this element is different from that for the eight-node brick (Brick8N) element.
  2. The valid queries to a Quad element when creating an ElementRecorder object are 'forces', 'stresses,' 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.
