Pang Yuhan Posted July 22, 2019 Share Posted July 22, 2019 Hi- I am a newbie using TOUGHREACT/PetraSim to simulate the Water-rock reactionmainly simulates the dissolution of calcite(mainly simulates the dissolution of calcite).I am using ECO2N (is this right for my purpose?)and got success in simple 2D model.I set up the chemical parameters with reference to the existing examples and run successfully.But when I try to change the chemical composition setting to the corresponding composition of carbonate rocks, there are always errors in operation. The program runs for a period of time (usually up to several years),then it failed with the error message "Simulation is halted Prematurely" yes, I think the system is too simple and there should be some more that it makes balanced, but I don't know how to make it.. Thank you. 跑出 Link to comment Share on other sites More sharing options...
Alison Posted July 22, 2019 Share Posted July 22, 2019 This is a TOUGHREACT error that indicates a "poorly defined chemical system". Typically, you would want to create a model in a separate program such as PHREEQC or GWV that defines minerals and water chemistry in equilibrium. You can then bring that into a TOUGHREACT model as initial conditions. Best Regards, Alison Link to comment Share on other sites More sharing options...
