{{CommandManualMenu}}

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

{|
|  style="width:150px" | '''$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:
#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,' 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.
