Mineral volume fraction greater than 1 in outsolid.dat

Hello,

I have a problem with TOUGHREACT PITZER. I'm running a model with calcite, anhydrite and dolomite whose initial volume fractions are 0.99, 0 and 0.01 respectively. Dolomite is specified as kinetic mineral whilst calcite and anhydrite are at equilibrium. In solute.inp (minflag) I specified to display the mineral abundances in the output as current mineral abundance in volume fraction. However in the output I get anhydrite abundance greater than 1 which should not be possible. Dolomite and calcite abundances are instead both comprised between 0 and 1. Did anybody else ever had a similar problem? how did you fix it?

Thank you

Tatyana
