GTSNX 2014 V2.1 Release Note 1.1 Embedded Beam Element Beam element must have a node connection with the surrounded element, otherwise embedded beam element can make a node connection with Mother element automatically. ■ Beam and Embedded beam element have the same DOF(degree of freedom), so can be used for the same purpose, but even a node of Embedded element cannot protrude from Mother element. Embedded Beam Element are available in both 2D and 3D. In case of embedded structures like pile foundation or pipeline umbrella for tunnel, embedded beam element can be used to model those...
