Konstantina Bourazani

Hello, I am very new to modelling with FEFLOW, and I cannot find any relevant online resources to help me with my problem. I want to model the saltwater contamination at a site, and then see if a freshwater bell will occur by injecting freshwater at a 30year period. I know the salt concentration for every depth so I have entered this as an initial concentration at every slice and also I have put the boundary condition as the same. so e.g the first slice i have entered 4000 mg/l on the whole slice as mass concentration and for boundary conditions I have entered 4000mg/l on the north/south border. I dont know if this is the way to go but when i run the model the first slice is always at a concentration of around 2900 mg/L in the center and a harsh line of 4000mg/L on the borders.  How do I fix this?  Thank you for your time.
