This command is used to construct a four-node 3D viscous-spring boundary quad element object based on a bilinear isoparametric formulation.

element VS3D4 $eleTag $node1 $node2 $node3 $node4 $E $G $rho $R $alphaN $alphaT


$eleTag unique element object tag
$node1 ..$node3 4 end nodes
$E Young's Modulus of element material
$G Shear Modulus of element material
$rho Mass Density of element material
$R distance from the scattered wave source to the boundary
$alphaN correction parameter in the normal direction
$alphaT correction parameter in the tangential direction
