Hi all,
I set up a 3D steady flow-transient transport model. I put a flow sink on the top layer, and the results showed that contaminant accumulated along the sink, and had a very high concentration (5 times higher than the contaminant sources) along the sink. What is the reason for this problem? When you put a sink there, is the contaminant also removed from the model domain? Or you have to put a contaminant sink there simutaneously? Any help would be appreciated.
