Dear Mr,

I was hoping you could explain me how it prepares the input file with
TRANSPORT function. I have simple situation: initial concentration of Cl-
in column is 0 mmol/kgw. I brought solution with 50 mmolCl/kgw in for 90
days and after that  solution without Cl- (initial concentration). I
tried to observe changes in time and what could happend in column after
one year = total time of experiment. I calculated that example in
CXTFIT  and  it worked. Results are completely different.
