Hi,

     I am trying to model how a fluid (with a small current) moves around an obstruction in a rotating fluid.  I have the object moving to simulate the current.  However the flow is not responding appropriately.  I had to change my pressure-veleocity coupling scheem to "coupled" for the calculation to run, otherwise I kept getting x momentum amg solver errors. I have the energy equation on.  

What could I tweak to produce the correct flow?

Here is a video of what I am trying to re-produce.
