The Store Simulation Properties dialog has only one page: General. The simulation properties of the store are flow logic rules. Flow logic rules specify which flows have to come into the store before some output flows are sent. E.g. the following rules:
Flow A+ Flow B -> Flow C
Flow B -> Flow C + Flow D
mean that when activation from flow B and activation of flow A enter the store, flow C will be activated. If flow B comes to store without flow A, both flow C and flow D will be sent.
