I've solved this issue.

If you try to export the hydraulic conductivity values from a *.DAC, it will fail.

If you open the corresponding *.FEM file, which we assume the conductivities will be the same for, the export will function normally.

Hi Bjorn,

Is there an example in 2D I can see?


Or a reference page...?

Thanks

Edit;
I think I've sussed it out.
Which columns are not needed? e.g. your example with Time2 = nan?

Not sure what you mean by 'sheet' here, hninanya. There is no 'sheet file' pre-existing and I expect the exported file to contain all of the rows.

It's a very simple task for most of the other exportable values, but for some reason the conductivity blows out.

Hi all,

I'm unable to export the hydraulic conductivity distribution from my models.

I expected this to work in the same manner as exporting mass concentration (or any other 'process variable') but trying to export the conductivity results in FEFLOW taking an absurd amount of time and generates enormous files.

I just want to plot the values external to FEFLOW.

The error from "Export data --> All elements --> as center" is:
"Table "F:\(exported filename): Conversion failure RecNo 10000000, Item "Id" (Type i -> l)"

Thanks Bjorn, that's what I was after!

Hello,

What's the correct format for time lapse observation files?

I'd like to ultimately integrate into FePest.

Thanks Bjorn.

(Sorry if this next question is a little abstract.)

Could you briefly touch on how the dimensionality affects the well boundary condition for a 2D cross section?

Obviously the Well BC relies on a volume of water at a constant rate, and the 2D cross-section assumes a thickness of 1 m[sup]2[/sup] (if I understand the online help well enough).

Does the volume of water only apply to the 2D cross-section, and then - how can that accurately represent a 3D volume of water affectecting the system? i.e. what are the in-and-out constraints applied to the 2D model? Does the volume of injected or abstracted water apply only in the 2D (x/y) plane, and then surely that will be overcompensating the effect of the injection on the groundwater system?

Great - thanks Bjorn.

Is there anything I can do to prevent 'upwards' flow from the well?

e.g. simulate the water injection through screened intervals?

When I tried to implement a well with a Discrete fracture condition as described, many of the streamlines were going straight up, as opposed to leaving the discrete fracture first.

Sorry if that doesn't make sense - I'll draw it out to try and describe better.

Hi all,

Is there a method (or a tutorial) on setting up a multilayer well for a 2D cross-section?

Cheers,

Thanks Peter, I found that one. That didn't fix the slices issue though, unless I missed something?
