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
eleNodes (list (int))	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

1. 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’, ‘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.
