I work for a company that makes blenders, so there is no inlet and no outlet for our product/fluid.  It is just in a tank and get mixed.  We don't currently have Flow Simulation Premium.  I saw with that, you can do analysis with a rotating object (i.e. blending blade).  Can you run simulations without an inlet or outlet, or do all simulation tests require an inlet and an outlet?  If it requires them, I'm guessing this software would probably do nothing for us.  Thanks.
