PHREEQC and PHAST version 3.3.2

New versions of all PHREEQC and PHAST programs have been loaded at
http://wwwbrr.cr.usgs.gov/projects/GWC_coupled
. Notes are given here for version 3.3.2 and 3.2.2 (the previous release).
Notes for version number 3.3.2 (svn 10335), October 2, 2015.
PhreeqcRM. A new method was PhreeqcRM, SetScreenOn (RM_SetScreenOn), to control messages about rebalancing and any messages written with ScreenMessage (RM_ScreenMessage). Fixed bugs in configure scripts that required developer zlib to be installed. Now zlib is only needed if the --with-zlib option is given in order to write compressed dump files (#define USE_GZ).
PHREEQC. A new R version has been submitted to CRAN.
PHREEQC. A bug was fixed when GAS_PHASE components were not defined in PHASES. Fixed bug with SOLUTION_SPREAD. Element names starting with "[" were not handled correctly.
PHAST. Minimum concentrations were lowered from 1e-14 to 1e-18.
Notes for version 3.2.2 (svn 10160), September 15, 2015.
PhreeqcRM. PhreeqcRM has been revised to decrease the memory footprint for MPI runs. The storage for about 8 variables was revised. Previously, each MPI process had a complete list of values for these variables (like saturation and porosity) for the entire model domain. Now, only values relevant to the cells that are associated with the MPI process are stored.
PHAST. In addition to the memory savings related to revisions in PhreeqcRM, the storage for MPI workers was streamlined. Many variables were unnecessary and were removed, both for processes that run only chemistry, and processes that run chemistry and transport. MPI PHAST now takes a single integer argument. This argument specifies the number of transport calculations that will be run simultaneously. The total number of tranport calculations is equal to the number of components in the system, normally 6-20. Decreasing the number of simultaneous transport calculations will decrease the total memory footprint of a calculation. If memory is not an issue, use the default (no argument) to run all transport calculations simultaneously.
PHREEQC. The pitzer.dat database was revised for parameters associated with CO2 and CH4 to better fit experimental data for solubility of mixtures of the gases. An additional line of output was added for Donnan calculations.
IPhreeqc. Fixed a bug in the Fortran version that allowed logical variables (for example, print control variables) to be set to TRUE, but not back to FALSE.
