Default Multiple steady state with same boundary conditions

faisal_durr is on a distinguished road

I am looking at Natural ventilation inside buildings. I have read many papers where for the same geometry of the building they acquire multiple steady states of the final ventilation flow. Experimentally they observe such phenomena by repeating the experiment a couple of times. I am now using LES to simulate such multiple steady states. Can some one advice me how to acquire them using LES? I mean if I run LES once on a geometry I will get one steady state right? But how do I get the other steady states for the same boundary conditions? Thank you
