The model in Example_CB10.zip is a simple example with chemistry module "Reactive transport CheMec. This model has been calculated with CODE_BRIGHT_2023_10.The main improvement here is that the initial conditions for chemistry are assigned by zones togeter with other initial conditions. The model uses 2 types of water that are assigned in diferent zones. The file Example_HC_equilibrium_CB10_chem_ini.dat contains the concentration of water types 1 and 2. The fille Example_HC_equilibrium_CB10_chem.dat contains the description of chemistry for 2 primary and 2 secondary species. =========================================================================================================== The models in Examples_CHEPROF.zip correspond to the module "Reactive transport CheProf". The models have been calculated with CODE_BRIGHT_2023_10.
