The error states that you are trying to set a multi-layer well (or BHE) at locations where already boundary conditions / other multilayer wells / (or BHEs) exist. Your choice is to either keep the existing conditions or overwrite with the new ones.

That's currently not directly supported, but will be in the upcoming release.

As a workaround (maybe faster than the ArcGIS option) you could set any type of BCs to the nodes in the selection and then use the conversion tool provided in the context menu for the corresponding BC type. Be careful with this as it a) will overwrite all BCs on these nodes and b) will convert ALL BCs of the type into an elemental selection.

The also work in variably saturated flow models, but: Discrete features connecting along the well pipe are switched off above the water table (at p<0) and pumping well nodes (placed at the botttom of the multi-layer well) are also switched off if they are on dry nodes (p<0).

What's the structure in the upper left corner? It doesn't completely look like a simple polygon to me. Is there a line overlaying the polygon border?

Could you specify more in detail what the error message is about?

The van Genuchten parameters show up on the levels below the Unsaturated-flow model type in the Data Panel. You'll have to expand the tree once to see 'Spline Models' and 'Empirical Models', and by expanding 'Empirical Models' you get the Van Genuchten parameters displayed.

It's indeed sometimes a bit tricky to select a polyline. The easiest option might be to move one node of the polyline to a location outside the polygons and then select the line by clicking on it outside the polygons.

Dear Jim,

You can export the head or pressure directly from the 'Data panel' by right-clicking and choosing the 'Export Data' entry. The file menu gives you several file formats (.shp, .dat etc.) to store the data.

Visualizing the water table in phreatic environments is done by plotting the pressure in the current view. I would suggest to use a combination of 3D view and 2D cross-sectional view.
In the 3D case, you can activate the 'Zero Isosurface' of the pressure in the 'View Components', in a 2D cross-section there is a 'Zero Isoline' available. See also the attached picture, where I visualized a strong gradient between an open pit and a river intersected by a sheet piling. Make sure 'Enable Lightning' is active in 3D views.

When you right-click on the 'Zero Isoline' entry in the 'View Components', your are also able to export the plotted isosurface or isolines in different formats  and you can reload them as maps in FEFLOW or other software.

The warning wants to say (maybe not very clear indeed) that the final time in TRNSYS has been set to an earlier time than the final time of the FEFLOW model. Thus the plug-in resets the final simulation time in the FEFLOW Problem Settings to the final time derived from the TRNSYS data. After this, the 'original value' is no longer visible.
