Dear Peter.
Now i facing "Convergence problem" for steady state.
The picture is the well position(cross section).
radial well 1: red star(elevation : 6-7m), 25,000 CMD
radial well 2: red start(elevation : 2m), 25,000 CMD
Just setting well 1, the simulation can get convergence(balance:1e-5). (however the saturation of elements near well zone approximated '0').
After setting well 1 and well 2, the simulation cannot convergence.
I have try to smooth my mesh, but it cannot solve.
I refer some papers and articles, i know the "Dry cell" will result in convergence problem in unsaturated flow,
but in my case, the well 1 is close to well 2 which cause my elements will be very small(easy to be dry cells).
Any suggestion about simulated convergence problem?
