Time varying BC and pumping rates

Hi everyone!

I´m new using Feflow.. and some doubts have appeared..

First, how can I set a time varying pumping rate to a multilayer well? I have read some documentation and I reached to the conclusion that I need to create a point in a shape file from the multilayer well in order to enable the "link parameters" option. And then, link the rate of the multilayer to a given .pow file. But I don't see how I can do it... Is this the right procedure?

Similarly, I´d like to establish Hydraulic Head BC in a boundary following a river which is quite close to the sea. Thus, I thought about setting a time varying HH-BC. How could I define this condition?

Thanks in advance!!

There are several ways to assign time-dependent pumping rates to Multilayer Wells (MLW's). The workflow you suggested is described in details by the Introductory tutorial:

Of course, you do not need to make a parameter link. If you have a small number of MLW's you could assign the time-series manually using the MLW Editor.

If you want to assign Head BC's along the river you could make a 1D interpolation along the trace of the river. The 1D linear interpolation is a method for interpolating linearly along line features provided by a map. It requires that in the Parameter Association dialog a line map is selected as Default Link Selection.

Thank you Bjorn very much for replying.

I read the tutorial but it still seems a bit confussing to me. If I´m not wrong, the only difference between a well and a multilayer well is the source of the pumping, right? Which is, a given node in the case of the well, and every node of a vertical or whatever is selected from the multilayer well editor, right?

Then, in the case that I want to create a link via parameter association dialog, I need a map (a shape file) in which I manually input every parameter needed in feflow, right?
But, if I want to define the pumping rate manually, I do not see where I need to stablish the link to the .pow file.

* In the case of a [b]well[/b], I dont see where I can choose the time varying option, where is it?
* In the case of a [b]multilayer well[/b], I enter the MLW editor and clicking in the capacity box, it changes from constant to time varying symbol, but, where do I need to select the .pow file I have defined for the well?

Thanks again!

The difference between a Multilayer Well (MLW) and a WellBC is the fact that a MLW is composed of a 1D Discrete Feature (DF) + a WellBC. A DF is an element of lower dimension and highly permeable. A WellBC can be considered as a nodal source/sink term.

If you want to assign a time-series for a MLW please do the following steps. Double click on Multilayer Well in the Data Panel. After that, go to the Editor Toolbar and double-click on Multilayer Well. In the Editor Toolbar click on the symbol within the Capacity input field to switch from constant values to the time-series mode. After you switched to the time-series mode you can use the drop down menu to select a time-series of interest. The time-series shown in the drop-down menu represent exactly the time-series strored within the time-series Editor.

I see..Thanks!!
The problem is that I wasnt loading the time series first.. After loading them, of course they appear in the drop-down menu :)

In this context, I´m getting an error when I try to stablish MLW properties that sometimes appear, sometimes dont..and I dont get to understand where it comes from.
It says Verify assigment-Invalid Data. At least one node belongs to at least two multi-layer Wells.

But, int fact, I´m just selecting one node.. Any suggestion, please?

Thank you,

Please assure you have an Edge selection active without any other BC imposed on the node connected with the edge.

Thank you very much Bjorn! The selected edge doesnt have any other BC. In fact, this error appear when I try to change the time serie, but if I delete the MLW and I load the serie I need, there is no error message. So, this solved!
