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 |
