Dear all,

I am stuck with FEMWATER transport simulation. I have a well calibrated
regional flow model that I have used to create transport model at a local or
finer scale using the total pressure heads as boundary conditions. My model
now comprises two polygons: the outside boundary with specified head and
flux (recharge) and a tailings impoundment in the centre with specified
flux. I now want to investigate the effects of dispersion on concentrations
of any releases from the dam. I have tried to speciffy the concentration in
tailings impondment but i am just getting zero concentrations in the output.

Please help
