Thank you very much for your instruction! I did it.

But I just did it with one parameter: the rainfall. I think I can edit the recharge from rainfall, evaporate, humidity, and temperature and elevation with some functions through the signal next to "in/out flow on top". I want to see 'Help' here but I have a warning: "Feflow 5.3\bin\wxhelp.exe not found".

I want to ask:

- where I can get some instructions in editing functions?
- how the recharge is calculated from meteological parameters and elevation in Feflow?

I hope to hear from all of you soon.

To be continued ...

After comparing all slice elevation with the bottom and top of well, I got trp files which are wells for each layer and common wells for 2 layers as well. Then I input these data layer by layer (assign database/Inverse distance weighting interpolation-1/Well/F2) and I always have many log messages:
"Well nesting: The generated well node ... could not desired vs. actual position : X:.... Y:..."

Could you please help me to know what happen?

Thank you!

Hello,

I have monthly data on rainfall, evaporate, humidity, and temperature in 10 years from 7 meteorological stations.

I think I need to assign them as time-dependent recharge in my regional model. I'm playing around with pow pnt files... but still don't find the way. : (

Could you please give me some advice.

Hallo,

With trp exported files I can have the thickness in points.
When I use Isoline/Finger I can see data in areas. In attributed data I have ID, Elev_l and Elev_h. I combine objects using ID to have less groups. I guess the thickness is equal to (Elev_h - Elev_l); however I realize that all the thickness here are the same (about 2 m).

I don't really understand the way they are calculated and how I can change some default values to get my target.

Thank you Mr. Schatzl for helping me step by step. I do hope to hear from you more!

Additionally, when I export the thickness as trp flie (save nodal quantities as points) I can see more data which I guess are the calculated thickness :)

However I find here many extremely small value (10.e-10). When I interpolate the slice elevation I have chosen minimum top and bottom distances are 0.1m.

I don't understand why there appear such small thickness values?!

I'm waiting for any ideas.

Dear Mr. Schatzl,

Thank you very much for your reply.

I still have a problem.
When I export the thickness into file .shp:
In menu Slice Elevation:  Special/z_coordinates/Thickness (option for operating)/Mesh (Save as plot file..).
I open this shp file in MapInfo and I cannot find the thickness in browser, just see Id (all of them are 1) and another attributed property called Elno (with continuous value from 1 to 30,556).
I also add this shp file as map in Feflow and use Mesh Inspector to see, and find just the elevation.

I don't know at which step I was wrong.

 

Dear friends,

I'm now having a 3 layer model (as unconfined, aquitard, confined aquifer at first). These layers are determined by elevation point data. When I import elevation data for 4 slices (with kriging as the interpolation method), there are intersection and I just adapt with default value (the distance is 0.1 m). I understand that where the distance between 2 slices is 0.1 m the upper hydro-geological layer is absent and I need to impose the characteristics of lower hydro-geological layer on these areas. It means that there are 2 'groups' of values in the same model layer.

But I don't know how to determine or to zone these areas in order to impose different characteristics (K, recharge,...).

Could you please help me?
Thanks a lot!

Thank you very much for your reply!

I'm now trying to do divide wells into layers as the following:
      - To add all wells as points in supermesh, them all of them become points in superelement.
      - To export all slice elevation as file '.trp'
      - To use the tool mix_trp with function "F=F1-F2" in cygwin in order to compare all slice elevation with the top and bottom of wells.

I have many times the error message in cygwin like this "C:\cygwin\bin\sh.exe:  *** heap allocated but not at 0x9C0000    3 [main] sh 7520 sync_with_child 6188 <0xF8> died before initialization with status code 0x1    396 [main] sh 7520 sync_with_child: *** child state waiting for longjmp /usr/bin/mix_trp: Cannot fork: Resourse temporarily unavailable"

Could you please explain it for me? And I still can get the result after doing it again and again without any change in data.

Have a nice weekend!

Hello,

I have the data of 1200 withdrawing points in the study area. For each point I have: X, Y, the top and the bottom, and the pumping rate. I want to import the data as 4th type (well) boundary conditions, but I don't know how to automatically import multi-layer wells and I also don't know how to find which layers these wells belong to.

Please give me some suggestions!

Thanks a lot!

Good morning
I have some rivers within my large study area. Along these rivers I have some monitoring stations with water level data in 10 years. For transient state I think I have to assign 3rd type boundary condition for these rivers with time-varying function.
In the link below I found this situation for a river as a boundary of the area and that the northern and southern points have the ID 1 and 2.
(http://feflow.info/317+M54a708de802.html)
Now I have a river lying in the area with 4 monitoring stations. So I have a powerfunction file with 4 powerfunctions (ID = 1-4). I don't know how to link these 4 ID with 4 points, and to interpolate along the river. Is there any difference in transfer rate between steady state and transient state?

I'm waiting for any help, please as detailed as possible.
Thanks a lot!

Thuy.
