2-D simulator setup for the DNAPL vapor
transport experiment defined by:
Lenhard et al., Journal of Contaminant Hydrology, V 19,
                pages 47-67, 1995.

Put the exe file in the directory IC and run from there (defines the initial moisture profile)
Then copy the *.rs files to directory Force.
Move the exe file to Force and run.

Subdirectory IC:
 defines the initial static water saturation profile which 
 is used as initial conditions for the DNAPL vapor forcing.
 Run this problem first, and then use the restart files
 as ic's for the problem defined in subdirectory Force.

Subdirectory Force:
 Given the initial conditions from the problem defined in 
 subdirectory IC (use *.rs files), compute the temporal and spatial distribution of
 DNAPL species in the water and gas species.

The bc_flow conditions are set assuming i_static = 1 (in include.f)

This problem differs from original in that the node-specific porosity 
is now set = 0.1 (origunally 0.01).  The lower value was too much of a discontinutiy 
for the code to handle.
