Grid is staggered...
- Velocity stored normal to faces,
- all other quantities stored at cell centers.
- Ideal for finite-volume formulation.
- Allows local and global conservation of energy and mass.
- Need to interpolate cell-centered values onto faces.
- Need to approximate tangential velocity component.

...not non-staggered
- All quantities stored at cell centers.
- All velocity components are stored.
- Conservation is approximate.
- Need to interpolate to obtain cell-centered
quantities at faces.
