That kind of difference may be caused by different values of the “source” term W between the FEA solution and the analytical model.

Dear Nagi,
In analytical model, "W" is defined as annual average rate of infiltration [LT^-1], but in comsol, I supposed for the upper boundary of rectangle "Inward flux", and I imposed value of Precipitation [LT^-1] as an infiltration rate.
So, is there any possibility that definition of Inward flux is not the same as infiltration rate for the analytical solution? How can I solve this problem?
Thanks in advance for your help
