Controls the use of large displacement and follower force effects and differential stiffness in nonlinear analysis. If LGDISP is set to 1, or ON, large displacement and follower force effects and differential stiffness will be included. If LGDISP is set to 0, -1, or OFF, large displacement and follower force effects and differential stiffness will not be included. There are six options:
In Automated Impact Analysis (AIA), if LGDISP is set to 0, a value of 1 will be forced. |
