How to editing already set Multilayered well BC

Hi guys,
can somebody show me the correct procedure to edit an already assigned multylayered well BC (Feflow 6.1)?

I've placed some of these BC in my model but I'm not able to vary any attribute (punping rete) unless I delete the well and completely re-assign it.

What is the procedure (or the right button) to edit a multilayered well BC?

thanks in advance.

Nobody can help?

An unsupported way to change it is by saving your fem file as ASCII then editing the file through a text editor.

Multilayer wells are defined in the FLOW_I_BC, MULTILAYER and FRACTURES (can't remember the exact names). What you likely want to change is the MULTILAYER well block -- it's presented in XML. Here you can change the elevations (uses the top and bottom nodes defined in the elevation range) and storage along with the other properties. It's trial and error to figure out what's what.

They're pretty hard to work with from what I remember. I don't think you can edit them any other way; you'll have to redo them to change them as the interface just shows the last inputs you made, rather than the assigned properties.

Ok,

there are not so many wells in my model, so I think I'll re-edit them each time.

many thanks adacovsk!

Dear Giuseppe,

Alternatively, you can edit the multilayer wells directly on the FEFLOW interface. Steps: 1) select the multilayer well, 2) go to the View Components panel, 3) activate Multilayer Well - Attributes, and 4) activate ONLY the attribute to edit.
You will notice that Editor toolbar will change to the attribute, e.g. "Rate (MLW)". Here you can just type the new value.

Two additional ways if you have several multilayer wells,

a) Use Link to Parameter (s) option in the Map panel to make the MLW assignment. Here, you can create a table (excel, text file, etc.) with all the attributes and link values to MLW. If edition is needed, you can edit your table any time (outside of FEFLOW) and then re-create the link again.

b) [b]This is the very fast option![/b] ONLY available in FEFLOW 6.2.
- Export all the values of MLW. Data panel and right-click on Multilayer Well. Here you can use a Excel file, text file, etc.
- Edit your tables
- Import your map file again
- In the Map panel, right-click on re-imported map and choose [b]Quick Import[/b]

[b]Quick Import[/b] option will make the assignment automatically. No further action is required here. The trick is that every time you export FEFLOW information, you have also values of node and element numbers. Therefore if you did not modify this topology, the Quick Import will know where exactly to place the assignment again. Operation is valid for nodal and elemental assignments.

Many thanks Carlos,

your post is very useful!

I'll proceed with installatione of Feflow 6.2 in the next days, license should be available for me.
