i want to study a vortex shedding

I have a pipe (inlet and outlet)-inlet with 1m/s and outlet to 1 atm pressure

and I have another inlet on the cylinderical surface of the pipe with some velocity of 1 m/s -this inlet is like a botle attached to the pipe-

now I want to study the vortexes created as the flow is comming out of this bottle and enters the pipe-

-for turbulant flow I like to use LES - i got a good result with k-e model-I set everything to automatic

but the model with LES doesn't produce any results-it runs to the end but the monitor shows a constant line and basically has no data when u look at it in postprocessor

what do u sugest? what am i doing wrong?

this study is going to be very intersting and I will give u more details as I MOVE ON
