Hi Axayacatl,
This functionality is also available in FEFLOW 6. You find it in the Spatial units panel (context menu) and in the context menu of the view(s).

Hello.

I changed job and the license they have is FEFLOW 6. I don't remember if the function of storing selections of nodes and elements is available also in FEFLOW 6 or just in 7?

Thanks a lot for your kind answers.

Let me anser your second question: Those constraints are put as FEFLOW does not require a fixed-concentration BC when water flows out of the system at a boundary. Thus it is good practise to apply the fixed-concentration BC only for water inflow - and this is what the constraint with a value of 0 does.

No, this has been new functionality in FEFLOW 7.0.

You can use either the Subdomain Rate Budget panel or the Rate Budget panel for an elemental selection.

Hi,
in steady-state the correct working of constraints ist not strictly guaranteed. They are evaluated once and then kept, as otherwise the model would very likely loop infinitely over finding the correct status. In such a case, where the spring BCs keep infiltrating water, I recommend to run the model in transient for a while. Once the correct water table is found, it might work to run scenarios in steady-state again (assuming that the conditions at the springs do not change much).

It seems that the phreatic surface in your model is being simulated with the 'free&movable' option. In this case, element deactivatoin is not supported. You'll have to either use the 'Phreatic' mode or a fully unsaturated model in order to use inactive elements.

Hi Boris,

FEFLOW does not allow to load ESRI ASCII grids directly. I recommend to export the mesh nodes as shp, attach the values from the .asc grid to the points in a GIS system, and import the elevations back to FEFLOW. Alternatively, you can convert the .asc grid to points and use these for interpolation in FEFLOW. The latter option, however, will give you a very large point file that is not required with the former one.

Here's what I do to avoid selecting slice edges as well: I use selection of join edges, and then convert them to edges after selection via the context menu of the current join edge selection. Same the other way round for seleting edges in a slice only.

I guess I should add [22 May 2017] that in FEFLOW 7.1 there's a selector for selecting both slice and join edges, or only one of the types when selecting edges. You find the switch on top of the current view window.

FEFLOW 7.1 has already been released. It can be downloaded from https://www.mikepoweredbydhi.com/download/mike-2017/feflow. Please note that the updater in FEFLOW only installes new minor updates, the major versions are installed separately. With this, you get the possibility to have more than one major version installed in parallel.
