RE left-handed grid, you've put you ijk origin in the wrong place. Shift it over to the other side of the mesh. If you're using a polar mesh, just rotate the circular plane around the other way.
To close the loop, you need to define some cyclic boundary conditions at the extents where the loop closes. |

i am working on single phase natural circulation loop. i have make grid in bfc for circular pipe which is a rectangular glass loop. the loop is filled with water. heater is placed at bottom & cooler is at top. i want to solve for velocites,press& temp.how to solve for this. how to get convergence
