Hi,
I'm trying to use COMSOL to model water infiltration and evaporation in porous media. Few questions in this issue:
1) How do I define a boundary as open boundary for Evaporation. How do I define the evaporation rates?
2) Can I add to the model vegetation with roots uptake?
3) How can I change the soil properties? In the material library there is only 1 soil with certain compositions. For example, how can I define that there will be no organic matter in the soil?
4) When I run a simple Richard's model over long time scales (few thousands of seconds) it gives me the message that it has problem to identify the initial conditions? How can I solve it?
Many thanks,
Uri Nachshon.
