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 associated with previously-defined NDMaterial object |
Should the element be required to compute a mass matrix, a consistent translational element mass matrix is computed. Rotational-inertia terms are ignored
