Hi, Peter,

I checked the flow and mass transport condition for a pumping well, and found there is no way to specify the mass condition with unknown concentration but known flow pumping rate. For flow, I specified the pumping rate at the nodes in 3D, and it's OK. For mass transport, because the concentration is part of the solution, we don't know the concentration in the pumped water. If we don't specify concentration at the pumping well, the concentration in the groundwater at the nodes of pumping wells is higher and higher because no solute mass is removed with pumped water. I think we have to specify a kind of boundary condition for transport (using the simulated concentration as mass concentration at the pumping-well nodes, automatically with the specified flow condition for pumping wells), do you know the easy way to implement?

Thanks a lot.
