2
Iso-surface plot of water colored with velocity magnitude (solid component is transparent to see the water surface) * velocity magnitude color scale shows the actual range of velocity values throughout the system (ft/s)

3
Iso-surface plot of water colored with velocity magnitude (solid component is not shown to see clearly the water surface) * velocity magnitude color scale shows the actual range of velocity values throughout the system (ft/s)

4
Iso-surface plot of water colored with free surface elevation (Plan view) (ft)

5
Iso-surface plot of water colored with free surface elevation (showing water surface elevation in the building) (ft)

6
