% - uses PHREEQC to first equilibrate ic w/ minerals and charge balance
%
% Sets up model by custom-creating the following input files:

%   2) *_ph.dat: PHREEQC interface package file (to link PHT3D to PHREEQC)
%   3) postfix: additional PHREEQC optiocecns 
% (the following files 4)-8) are MT3DMS input file formats)
%   4) *btn: basic transport package file
%   5) *ssm: source/sink mixing package file (not geochem reactiions, 
%      corresponds to stress packages from MODFLOW)
%   6) *dsp: dispersion package file
% (the following files 7)-8) are set up the same each time in this script)
%   7) *adv:advection package file
%   8) *gcg: GCG solver package file (iterative scheme to address stability
%      problems due to time step)
%
% _Orgcsource (3/31/16): adds another immobile component that is source
%   that continuously replenishes Orgcsed.  For steady-state:
%
% Assumes pht3d_databas.dat (geochem database) file already exists; specify
% in 'use_file_databas'.
