kevinning51 Posted November 11, 2012 Share Posted November 11, 2012 When I am trying to run simulations of water evaporation, reaction of groundwater and mineral phase (among others) I keep getting this error message: N-R didn't converge after 999 its., maximum residual = 1, Xi = 0.0000 I tried to make the simulation as simple as possible, but the software still indicate errors. the script is as following: > data = "C:\Program Files\Gwb\Gtdata\thermo.dat" verify > time start = 0 day, end = 1 yr > length = 20 cm > left = inlet > right = outlet > Nx = 20 > discharge = 5 m/yr > porosity = .3 > scope = initial > H2O = 1 free kg > Na+ = 0 mg/kg > Mg++ = 0 mg/kg > Ca++ = 0 mg/kg > K+ = 0 mg/kg > balance on Cl- > Cl- = 0 mg/kg > SO4-- = 0 mg/kg > HCO3- = 0 mg/kg > pH = 7 > scope = inlet > H2O = 1 free kg > Na+ = 1585 mg/kg > Mg++ = 176.5 mg/kg > Ca++ = 50 mg/kg > K+ = 46 mg/kg > balance on Cl- > Cl- = 2300 mg/kg > SO4-- = 320 mg/kg > HCO3- = 14.2 mg/kg > pH = 8.2 > TDS = 45000 > react -3e3 kg/m3/yr of H2O Quote Link to comment Share on other sites More sharing options...
