Hi everybody!

I'm trying to put salt in my model but i sure i do not very well.
As many coastal aquifer the boudary of my model is not the real "rock" limit. More precisely, the limits of my model are vertically while the "rock" slope underwater is about 20 at 25% outside the model.
So my first question is how to translate this reality in our "[i]feflow vertical boundary model[/i]"??

My model: 15 layers ; 16 slices
I put 0 mg/l at the first slice
        2.5 mg/l at the second
        5 mg/l at the third
        7.5 at the fourth
        etc....
        .....
        35 mg/l at the 15 slice

Many errors messages like this appears in my log panel with différents values for "res_n" and "res_ini":

"[b][i]WARNING: BiCGSTABP matrix solution in 1000 steps
(> 1000 maximum iterations)
with errors: res_n = 7.490374e+02, res_ini = 2.128116e+06[/i][/b]"

what does that mean "res_n" and "res_ini"??

Is there somebody able to explain me how to do..

Regards
Terry
