Hi bgourley!

Thanks u tell me add layers in FEFLOW, it help me to save lots of time .(I always add layers by coding, it need to export and import elevation data).

And the table reference:
https://www.researchgate.net/figure/1-Van-Genuchten-parameters-and-saturated-hydraulic-conductivity-K-s-for-soil-layers_tbl13_256546124

And Durchlassigkeitsbeiwert!

Thanks u so much, you help me more understand van genuchten parameters!

I think i need to look more article about unsaturated simulation and van genuchten model.

And my case is part of GWF.

Jimmy

Thanks reply!

I gave the van genuchten parameters by the picture table(reference  Dirk Mallants).

However, cannot convergence after recharging.

My aquifer1 have gravel, sand; aquitard1 is clay; and i inactive aquifer2 now.

And i confused "increase discretisation", is it means let my aquifer1 layer be more layers?

Jimmy.

My model have 7 layers :aquifer1(layer1~5 which discrete equally), aquitard(layer6), aquifer2(layer7).

My elevation are picture1 and 2.

I have set a reasonable recharge and conductivity.

However the head always get very low(~-1e19) in the slice1 and slice2(domain left) which show in picture3.

The budget show not convergence: Imbalace:-132.26

But the slice 3~ slice 8 get a reasonable head.

I have no idea with this error.

The first time i used FePest.

And when i click on check, i got a error " Invalid argument pass".

What's this error mean?

Thanks!

Ok!

Thanks~

I want to import a package to FEFLOW, how can i do in the FEFLOW API?

Or how can i do the "pip install" in FEFLOW API?

If I want to know the mesh quality in FEFLOW.

How can i get the the mesh quality by jacobian ratio.

My elements type is triangular prism by gridbuilder.

Thanks!

The same question i faced today.

the first parameter "nId" is mean the EdgeSelections number which item had been stored(the picture).

ex:
doc.setMultiLayerWellAttrValue(1, 0, 1000), the "1" is mean well_1 item; the 0 is mean Rate setting; 1000 is mean 1000m3/d.

I use python plugins, but i don't know how to set a multilayerwell-BC.

I consider the parameters in this function, is (nNode, Attrnumber, pump rate). < right?

When i code "doc.setMultiLayerWellAttrValue(3247, 0, 1000)" in plugins, it return invalid MultiLayerWell Node id and range 0.0!

What's the problem mean?

And i want to know how to set different pumping rate in different depth?

Thanks!

(I solved this problem finally!)

I want to set a different conductivity(Kxx) in a vertical range(depth).

ex: Let the depth 100m-160m be a region which's conductivity are 1e-4.

And the output Kxx data from FEFLOW is element data.

but the region depth 100m-160m need to subtract "dem"(Digital Elevation Model) firstly.

So, I need to find all the elements which nearest slice-1, and use these elements's elevation(center Z) to subtract "dem".

then can correctly define the vertical range.
