The discrete data in the BoreHole.MRF file has been used as the initial state for a sample run of the PORFLOW groundwater transport model.
Now you will use the time controls in savi3D to display the predicted development of the benzene spill.
The initial system consists of a sandy-soil medium with a straight-line, left-to-right, flow. A drinking-water well pumps water near the upper-right corner of the slice (as displayed on the next page) and a smaller remediation-well draws water about 16.5 meters upstream from the drinking well to try to capture the benzen spill before it reaches the drinking water well.

Click on the Step Forward button (the right arrow with a line at the point) at the top of the savi3D Controls window.

The streamlines change, indicating a change in flow towards the two extraction wells.
The date changes in the Time display with each frame.
Frames in this DataSet are at two week intervals.

Click on the play or Animate Forward button (the unstopped right arrow) to automatically step through the 26 frames of model-output.

While animating, note the movement and change of the plume as the concentrations of benzene change and move, eventually dropping below the 1.0 ppb set for Iso1.

Try the Step Back, Animate Back, and Stop buttons. After you understand their function, click on the Stop button and continue to the next step.

Hit the Time Reset button (located just below the frame controls).

This sets the first time step as the current frame.

Step forward one frame to get your screen to match the image below.
