one layer coastal aquifere model

Hello everyone;

i have a one layer coastal aquifere model,

when i assign all the boundary conditions plus the material properties and i simulate in gives me hydraulic heads on slice 2 (bottom slice)

and for slice 1 (top slice) it gives me hydraulic head =0 as shown on the photos attached;

i can't figure out what could be the problem !!

any help???!!!!!!

Also on your bottom slice hydraulic head is zero nearly everywhere - only in a few nodes it is higher. You should definitely check your boundary conditions in this model.

thank you Peter Schätzl for replying me

does the well's radius affect the results because i don't have the radius data??
