4.2.16.4. ASI3D8¶

This command is used to construct an eight-node zero-thickness 3D brick acoustic-structure interface element object based on a bilinear isoparametric formulation. The nodes in the acoustic domain share the same coordinates with the nodes in the solid domain.

element('ASI3D8', eleTag, *eleNodes1, *eleNodes2)

`eleTag` (int)	unique element object tag
`*eleNodes1` (list (int))	four nodes defining structure domain of element boundaries
`*eleNodes2` (list (int))	four nodes defining acoustic domain of element boundaries
