Hi, anyone help me on how to remesh my 3d layered model based on some polygon such as geology?
i want some nodes in boundaries of each geological zones

If I used In/outflow for evaporation, how can I assign recharge??

If im doing sea water intrusion modelling, should i need to give recharge from top of aquifer any mass boundary condtion or feflow will take rainfall recharge as 0mg/l?

What is the reason for SAMG: Row(s) with negative diagonal found! ERROR
How can i rectify that?
       

any way to directly import precipitation to feflow and the change recharge according to each zones based on some percentage of precipitation?

Thank you so much

u can change transport state in problem class.
second question is not clear for me. Add some screenshots

How can I get the continuous simulation of actual water table to compare it with the observed groundwater level? because in first slice head is high and in lower levels it is decreasing

in an unconfined aquifer, observation wells for the hydraulic head should be at top of aquifer or bottom? while checking simulation I notice that first slice have high head value and when I go down it decreases

Thank you! Just seen the white paper for hydraulic head boundary in density-dependent flow.

I have one more question:

How to define tidal boundary condition? Do I need to define different time series for each node of the seaside boundry since with varying time tidal water level might go below the nodes in inter tidal zone?

From previous post I have seen there is a plug-in for varying saltwater head.

Do I need to get the plug-in below or FEFLOW 6.2 included the update for the same?

Thank you,
