mass conservation at pumping wells???

Hi there,

I wonder if in mass transport simulations, the concentrations at observation points located at nodes corresponding to pumping wells are representative of water fluxes and concentrations entering the well from all surrounding cells - including for wells connected to more than one layer (i.e. mass conservation)?

thanks

The concentration at the extraction node is a mixed concentration of all contributing elements, also in multi-layered wells. Mass conservation can be assumed as far as it can in all finite element calculations which do not strictly conserve mass on a local (element) scale.
