Michael makes some good points to consider.

However, to answer your question, you can define the snubber either in the model itself, or in the dynamic input - BUT NOT BOTH. If you put the snubber in the model, it will only be considered in a static analysis if the load case is OCC and/or you check the "activate snubbers" checkbox in the Static Load Case Editor.

Snubbers will always be considered in a dynamic analysis.
