Periodic vs Cyclic vs Symmetric

      Which one should I use for this regen cooled combustion simulation. Cyclic only seemed to repeat it 4 times, and I only got periodic to even show up in fluent one time, and haven't gotten it to work since then

      It depends. Do you expect to see swirl in the system?

        I am going to guess no

      If there's no swirl I'd expect cyclic and symmetric to give much the same result. If there's swirl you'll need cyclic/rotational periodics.  Note, if you're only seeing 4 repeats check in the Views panel as you've not set enough copies.
