Equilibration with several solutions

[MichaelZ20]

Good evening!
Could somebody explain why running the attached file gives the doubled results?
When I use many solutions (20), I don't receive selected output file with "punched" results.
Thank you in advance for any suggestions.

The SOLUTION_SPREAD and SELECTED_OUTPUT 2 definitions both occur before the END, so SELECTED_OUTPUT 2 is written to A.prn for the initial solution calculations for both solution 1 and 2.

Here is another option:

Code: [Select]

SOLUTION_SPREAD
units mg/l
Number pH Temp Ca Mg Na K Cl S(6) C(4) Br Si Sr Density
charge as SiO2 calculate
1 7 25 109 49 138 4.6 280 24 393 1.1 24 3 1
2 7 120 109 49 483 41411 37822 24 393 1.1 24 3 1.1
END
