For the boundary conditions you can use Assign - database - Import Time-varying IDs - Head BC - Automatic regionalization.

I understood what was wrong. I have to define a power function for each node I import and in trp file I have to put the ID of the power function for the selected node. By the way this procedure is quite tricky and very hard to set up. As I asked before , is it possible to use the pressure instead?

Peter,
I am facing the problem to assign a time variant seepage boundary condition

I am trying to follow your procedure but it seems that it does not work:

when I use the command:
Assign - database - Import Time-varying IDs

and when I select the *.trp file, I get this error message:
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.

WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: There are MORE unknown time-varying functions. Skipping all ...

the same trp file works fine when I import it a a time-constant data file.

PS. As Feflow allows to assign the pressure instead of the head as 1st boundary condition, why isn't possible to assign a power function for the pressure ? I tryied that but the command "pressure" is disabled when I try to use a time-variant function :(
It would be easier to deal with the pressure as it would have a constant value along the seepage face and I shopuld not have to define a different time-variant function for each node.
