AkuI Posted March 27, 2013 Share Posted March 27, 2013 Hi I have two problems with my model file. I am trying to model 1d column model where there is 50ml water in both ends of the column and clay in the middle. The diffusion problem works fine. The clay in the middle has it's own water inside which calculates the ionexchange sites correctly. The water cells have only 0.1 molar NaCl in equilibrium with CO2 partial pressure of 1 bar. Both ends have inlet condition the same as the water cells. First problem is that the model assumes that every cell has ion exchanger phase. Can this be somehow changed because ion exchange is not coupled to any mineral the sameway as surface complexation file. Can it be coupled or somehow done differently only to those cells with clay? The second problem is that GWB somehow calculates equilibrium to those water cells at zero timestep with minerals in clay phase when there is supposed to be only 0.1M NaCl present. Why is that? the nodes for water are 0 and 11 and 1-10 are clay cells. Can you help me? attached are database, ionexchange and surface files and the model file. -A MX80IonEx.dat MX80Surfthermoddem.dat Testi1atmCO2.x1t Thermo_thermoddem.zip Quote Link to comment Share on other sites More sharing options...
