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
