element F21 (1) (2) (3) (4) [5] [6]
# (1) int, unique element tag
# (2) int, node i
# (3) int, node j
# (4) int, section tag
# [5] int, number of integration points, default: 6
# [6] bool string, nonlinear geometry switch, default: false

Remarks

  1. The Lobatto integration is used by default. The number of integration points ranges from 3 to 20.
  2. To use the corotational formulation for nonlinearity, please turn on the switch.
  3. Unlike 3D beam elements, there is no need to attach an orientation to 2D beam elements.

Output Type

The F21 element additional support recording element deformation and resistance via the BEAME and BEAMS tokens.
