4.2.9.2. Bbar Brick Element¶
This command is used to construct an eight-node mixed volume/pressure brick element object, which uses a trilinear isoparametric formulation.
- element('bbarBrick', eleTag, *eleNodes, matTag, <b1, b2, b3>)
eleTag
(int)unique element object tag
a list of eight element nodes in bottom and top faces and in counter-clockwise order
matTag
(int)tag of nDMaterial
b1
b2
b3
(float)body forces in global x,y,z directions
Note
Node numbering for this element is different from that for the eight-node brick (Brick8N) element.
The valid queries to a Quad element when creating an ElementRecorder object are ‘forces’, ‘stresses’, ‘strains’, 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.
