Giuseppe Mandrone If you have values for a single time in space:

1. you go to maps panel -> add map -> you add your file with the points in space and their corresponding values

2. edit link, at the file you just loaded

3. In the Parameter Association window that pops up pair the values from your file on the left hand side to the hydraulic head parameter on the right hand side

4. select your preferred Data Regionalization Method, units etc and press ok

5. Again at the the maps panel and your linked attribute you right click and press Activate Link for Data Assignment

6. Enter a proper number for snap distance so FeFLOW will select the node closest to your data points, make sure that the data points are activated by double clicking the load file with the maps panel (double click the name and the "Default"), select by Map point in the selection toolbar, press Select by All Map Geometries when you have active the Hydraulic head process variable from the data panel and press the green tick sign to assign

That's it.

Hope it helps.
