This command is used to construct an eight-node 3D brick acoustic element object based on a trilinear isoparametric formulation.

element AC3D8 $eleTag $node1 $node2 $node3 $node4 $node5 $node6 $node7 $node8 $matTag

---

$eleTag	unique element object tag
$node1 ..$node8	8 end nodes
$matTag	Material Tag of previously defined nD material
