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.
