example 22 lists multiple errors and warnings
« on: February 13, 2017, 10:08:30 PM »
I ran example 22 in both the Linux and Windows versions of phreeqc.  While I still get a plot in the windows version there are multiple errors and warnings that come up. Can anyone please explain how the example simulation works, why a graph still displays even though there are problems such as:

Initializing...                                                                 
Simulation 1

ERROR: Could not open tsv file for USER_GRAPH co2.tsv
       Please, give the full path + filename.

The "ERROR" says that there is no file named CO2.tsv. Apparently, this file has been left out of the PhreeqcI distribution, but is present in the batch PHREEQC distribution. It is attached here.

The other warnings indicate that the numerical method tried more than one set of convergence parameters. As long a you do not get the ERROR message that the program failed on all sets of convergence parameters, your results should be correct.
