  1. Hey, I attached react and a surface data file that I have used in that react folder. This model should give me results of precipitation, dissolution, adsorbed/desorbed species related to co2 concentration in the system. However, except calcite (which has a significantly higher kinetic rate constant), I can not see any change in the other minerals in terms of mg. I tried using longer time intervals, still change in other minerals are 0 mg. I expected to see dissolution of albite, illite (which I see very small change) and precipitation of kaolinite and quartz. I would be happy if you could
  2. Thank you! RETURN worked! Ozan
  3. I am trying to use the rate law attached in GWB react. I tried to define a custom rate law and wrote a script. However, calculated rate is not correct and does not change through time. I would be happy if you could help me with this. The script I wrote is below. Here is the publication I used for rate law https://pubs.usgs.gov/of/2004/1068/ . I would also be happy if you could let me know if there is any way to put three different k and E values without defining a custom rate law. Thank you! LET kacid = 5.012 * 10^(-1) * 10^(-4) LET kneut = 1.549 * 10^(-6) * 10^(-4) LET k
  4. Hey, I am trying to built a sorption database according to minerals and elements that I am interested in. I encounter so many surface complexation models such as; Constant Capacitance (CC), CD-MUSIC (CDM), Diffuse Double Layer (DDL), Extended Constant Capacitance (ECC), Ion Exchange (Iex), Non-electrostatic (NE), Triple Layer (TL), 1pK-Basic Stern (1pK-BS). I know that (from GWB Essentials) GWB can use two-layer surface complexation which includes constant capacitance, constant potential and Ion Exchange. My question is about DDL which is also double layer and I guess it is equal to const
  5. Thank you very much! I will be careful about that. Best, Ozan Turkes
  6. Hi, I am getting the error 7466 ; The return of the fulfillment is denied by the return policy because max return exceed. I would be happy if you could help with this issue. Thanks! Ozan
