Hi,

Has anyone attempted variable-density thermohaline modeling in FEFLOW 6.0?

I have set up a simple model attempting to simulate the injection of freshwater into saltwater. In Mass Transport Mode, the model shows density-dependent flow effects, however if I try to set up the same model in Thermohaline Transport mode (even with no Heat BCs set), the solute-dependent density effect disappears! If I introduce Heat parameters (BCs etc) I see density effects due to temperature, but not due to solute. Thus it appears that the density coupling is only responding to temperature in thermohaline transport mode.

Cheers,
James.
