Release of:
Database
llnl.dat
PHREEQC Version 2.3 (Batch
version)
PhreeqcI Alpha 2.3-2010 (Windows
interactive version)
Database llnl.dat:
Greg Anderson has made a
PHREEQC database that implements most of the
inorganic aqueous species and
minerals in the thermodynamic data compiled
by Jim Johnson of the Lawrence
Livermore National Laboratory. This
compilation includes many elements not
available in any other PHREEQC
database. Many of the aqueous species and
minerals, but not all, are fit
over the temperature range 0-300. The database
llnl.dat should give results
essentially equivalent to EQ3/6 and Geochemist's
Workbench. The database
llnl.dat requires version 2.3 because it relies
on a new keyword
LLNL_AQUEOUS_MODEL_PARAMETERS to define the activity
coefficient parameters
and their temperature dependence for the Lawrence
Livermore model for
activity coefficients.
PHREEQC Version 2.3 (Batch
version):
A new DATABASE keyword was added to allow explicit definition
in the input
file of the thermodynamic database file to be used. A new
keyword
LLNL_AQUEOUS_MODEL_PARAMETERS and new identifiers to SOLUTION_SPECIES
were
added to implement the Lawrence Livermore database llnl.dat. A new
Basic
function (Surf) allows printing of the total moles of an element in
the
diffuse layer in surface complexation modeling. A new option to
allow
minerals to dissolve, but not precipitate, has been added
to
EQUILIBRIUM_PHASES. An option was added to the PRINT data block
to
eliminate echoing the input file to the output file. Several bugs have
been
fixed, for more information see RELEASE.TXT in distribution or the
status
page at
https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc.
Current
versions for Windows, Linux, and Solaris are now available at
https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc
and will soon be
added to
http://water.usgs.gov/software.
PhreeqcI
Alpha 2.3-2010, (Windows interactive version):
The interface has been
redesigned to handle multiple input and output
files. Multiple files can be
viewed within the frame of the interface. A
tree structure is created
to navigate more simply through output files.
Screen input for additional
keywords has been added, including all data
blocks that use the Basic
interpreter. Screen input is still lacking for
transport calculations and
thermodynamic data. Even though screen input is
not available for all
keywords, files using all features of version PHREEQC
2.3 may run either by
opening an input file or entering lines through the
line editor in the
interface. Current version is now available at
https://wwwbrr.cr.usgs.gov/projects/GWC_coupled/phreeqc
and will soon be
added to
http://water.usgs.gov/software.
