David, I am trying to simulate oxidation of arsenian pyrite. One scenario is complete loss of pyrite with the co-precipitation of arsenic in goethite. The following input file will not converge after the pyrite is completely oxidized in the first cell. Is there a way to continue the simulation with not pyrite in the first cell but with continuing oxidation in the second cell? I am using version 2.2. Thanks for the help. (See attached file: as5.fe0.pqi) Best regards, Alan Welch U.S.Geological Survey 333 W. Nye Lane Carson City, NV 89706 Office: (775) 887-7609 FAX: (775) 887-7629 ahwelch@xxxxxxxx
