B,<num>,<group>,<spgroup>,<bbc>,<force>,<end1>,<end2>

Defines a nonlinear beam and its properties for the NONLINEAR module. This command associates already defined beam element(s) with a backbone curve. This command does not make any new elements, change material, or any other properties of the beam(s) defined by other commands.

• num - Beam Number
• group - beam group number for the nonlinear beam
• spgroup - spring group number that is connected to the end of the beam
• bbc - backbone curve used for the beam definition.
• force - force option
• end1 - element at one end of the beam.
• end2 - element at other end of the beam.
