dirk Posted February 3, 2020 Share Posted February 3, 2020 Hi, I am running a simulation of a flow through column experiment and slowly working up to the full rtm. I run the initial solution through for 5 days then the contaminated solution. calcite reacts based on kinetic constraints, precipitation of gypsum, gibbsite, Fe(OH)3 at equilibrium all else suppressed, adsorption using the D&M model and the FeOH database (decreased site densities of w and s sites by an order of magnitude). after adding adsorption I cannot get it to finish. current error is "Step is constrained by rate of increase in length of reaction step at node 0." after 8 days of 10 day run. Any ideas? Dirk Quote Link to comment Share on other sites More sharing options...
