Question

Although I have selected "simultaneously" for several load cases within one action category, load combinations are also generated that do not act simultaneously.


Answer:

In this case, simultaneous action does not mean that the load cases must occur simultaneously, but they may (see Image 01).

If the loads are always to act simultaneously, it is also necessary to select the "Individually/Simultaneously Acting Load Cases" option (see Image 02).
