LES Time Statistics
 

I am trying to run a LES simulation in Fluent. One of the things I need to know is how Fluent stores the data for statistics. I intend to run the simulation for 40000 time steps with data sampling done with 10000 time steps. So I want to know where Fluent will store the data. I also want to know whether I have to store data file at each time step. Any help in this matter would be welcome. Thank you.
