Most important new features (relative to version 2.18):
- Precise calculation of gas-solubilities with the Peng-Robinson Equation of State.
- Pressure effects on mineral solubilities.
- Multiple USER_GRAPH's with flexible -plot_xy function. It is possible
to define line and symbol properties in addition to
graph_x, graph_y from PfW. Used extensively in the examples, see, ex6 and ex19.
Note that zedgraph.dll must be in the directory of phreeqc.exe.
- INCLUDE$ that allows to read in other files into the input file, and
to execute them. The files can be written during the run with
USER_PUNCH. See ex8 and ex21.
- .._MODIFY keywords that permit to change any model property, see ex20.
PHREEQC version 3 is installed in c:\phreeqc and subdirectories:
- MANUAL: the manuals and help file phreeqc.chm.
- EXMPLS: the examples from the manual. Run them with p.bat in a DOS window, for example:
p ex8.phr
It will show 2 graphs and write the output file ex8.phr.out.
Or, better, use Notepad++, see below.
- DATABASE: various databases.
- NP++: batch files that run PHREEQC tools from within Notepad++.
- PRESSURE: input files showing pressure effects on gas solubilities, scaling minerals. Run them with p.bat or run_all.bat in a DOS window, or with Notepad++.
Notepad++ is recommended for writing, editing and running PHREEQC 3 input files.
Notepad++ provides:
* syntax highlighting
* autocompletion
* calltips for BASIC functions and KEYWORDS
* colored numbers (1 and l are differently colored!)
* bracket matching: print (1 + 9.0) / (9 + 1.0)
* (un)commenting multiple lines at once
* column editor for easy BASIC line renumbering
* shortcuts: e.g., Ctrl+F6 calls PHREEQC on the current file
* file recognition on extension: .ppi .pqi .phrq .phr .dat .out
* Sections in between a '#[' and a '#]' can be folded up.
Notepad++ will be installed along with the phreeqc3 files in your computer.
Details are in the file c:\phreeqc\np++\Phr_in_NP++.txt.
