To make it even more clear I include this text part from the User Guide:

Quote:
For example, if a +Y support is active in the static operating case (normally
case 1 or 3), and the operating case is used to set the status of the nonlinear supports for
dynamics, CAESAR II installs a double-acting Y support at that location for the dynamic
analysis. The pipe will not move up or down at that point regardless of the dynamic load
or tendency to move.


This is the kind of behaviour I am looking for, EXCEPT that I want the status of the +Y support control the behaviour of X and Z.
