% - uses PHREEQC to first equilibrate ic w/ minerals and charge balance
%
% Sets up model by custom-creating the following input files:
%   1) *nam: namelist file 
%   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)
%
% Assumes pht3d_databas.dat (geochem database) file already exists; specify
% in 'use_file_databas'.
%       
%
% Uses the following functions:
%   - SC_InitCond_chem_2()
%       Specifies observed conc, equilibrates with PHREEQC
%   - Alk2DIC()
%       Called by SC_InitCond_chem(), converts alkalinity to total C(4)
%   - generate_ic_PHREEQC_f_062215a()
%       Called by SC_InitCond_chem_2(), generates equilibrated ic using
%          PHREEQC
%   - go_PHREEQC2_4()
%       Called by generate_ic_PHREEQC_f_062215a(), runs PHREEQC
%   - PHT3D_ph_f_general4()
%       Creates pht3d_ph.dat
