Product Name: NAPL GUI PIE
  The NAPL GUI PIE is a powerful user-friendly Graphical User Interface (GUI) for the Non-Aqueous Phase Liquids (NAPL) simulator, integrated within the Argus Open Numerical Environments (Argus ONE) modeling environment.

The NAPL GUI PIE allows the user to automatically input all data, run NAPL, and visualize the results all from within Argus ONE easy-to-use graphical workplace. NAPL GUI PIE installs its menus and dialogs into Argus ONE so that all tasks of setting NAPL control parameters, running NAPL and visualizing output is performed from within Argus ONE.
Model: NAPL Simulator (Ver 1.0 - Oct. '97)
Application:
Simulation of the contamination of soils and aquifers which results from the release of organic liquids commonly referred to as Non-Aqueous Phase Liquids (NAPL)
Processes:
The phase flow and contaminant transport simulator is applicable to three interrelated zones: a vadose zone which is in contact with the atmosphere, a capillary zone, and a water-table aquifer zone. Three mobile phases are accommodated: water, NAPL, and gas. The 3-phase k-S-P sub-model accommodates capillary and fluid entrapment hysteresis. NAPL dissolution and volatilization are accounted for through rate-limited mass transfer sub-models.
Miscellaneous:
The numerical solution is based on a Hermite collocation finite element discretization. The simulator provides an accurate solution of a coupled set of non-linear partial differential equations that are generated by combining fundamental balance equations with constitutive thermodynamic relationships.

The model accommodates the following boundary and external flux conditions: Dirichlet data for flow is specified as either one of the three phase pressures known (i.e., water, NAPL or gas), or all primary flow variables known (i.e., pressure and saturation); Dirichlet data for contaminant transport is specified as known species concentration; non-zero flux conditions for a phase or species within a phase are accommodated by specifying an appropriate point source/sink (i.e., a well); a mixed boundary condition is used to model gas-phase diffusive mass flux at the ground surface.

PIE Availability: The PIE and other related files can be downloaded from:
  http://www.argusint.com/pub/ArgusPIEs/PC_PIEs/NAPL/

This directory contains the NAPL simulator source code (FORTRAN), executable (DOS, compiled for max grid dimensions 61 by 41 nodes), the documentation, and some example problems for use with the GUI Argus ONE (http://www.argusone.com) and the PIE 'napl.dll'.

This version of the 2-D code is slightly different from that which is posted on the EPA/CSMOS web page (http://www.epa.gov/ada/napl_sim.html). The differences are explained in the documentation contained herein. Specifically, Ch 7, and Appendix F are the relevant replacements for those in the general documentation (available at the EPA site).

The zipped files are:

  • GUI.ZIP - the napl.dll (ie, the Argus ONE GUI PIE)
  • GUI_FOR.ZIP - the DOS compatible fortran source code
  • GUI_EG.ZIP - example files of the problem described in the documentation
  • GUI_DOC.ZIP - the documentation in PDF format.
  • napl2d.zip - the executable code (for max grid dimension 61 by 41)
  • project.pdf - presents a modeling project aimed at getting the user familiar with the capabilities of the PIE and the simulator.
  • course.pdf - walks the user through the tabbed menu of the PIE and explains the meaning of each input parameter

Additional examples will be posted over time.
