What does the "Different" effect mean when I define the action categories?


If load cases are combined in action categories, you can define how the load cases behave within an action category in the Action dialog box.

All load cases of the action can be combined as required. They can occur in a combination at the same time, but do not necessarily have to.

Of the load cases of the action, only one can be effective (e.g. wind from different directions). 

You can define detailed relations between the load cases of an action. If you select this option, an additional column appears in the Load Cases in Action dialog section. There you can assign load cases to a Group so that they are mutually exclusive (as is the case for the action Alternatively). You can select the number of the group from the list.
