hi  ;D
this message for Mr. petter
i have aquifer consist of 2 layers: upper aquifer is  unconfined aquifer and part of lower layer is unconfined and another part of lower layer is confined.
How to explain this difference in the model  with the should be pre-selected between either confined or unconfined.
I want to work the calibration  for the model in the transient state so I want an example of how to enter date  into the model under the transient state. 
  and thank you very much
