Which FEFLOW Update (patch) are you using? Please let me also know the operating system and whether you use 32 or 64 bit.

Your picture indicates on oscillating imbalances.
I recommend to use the automatic predictor-corrector time-stepping scheme. Apart from that, please check the following options:
[list]
[li]In most of the cases, oscillations are triggered by a mesh which is not fine enough to account for strong gradients and/or sharp contrats in material properties. Of course, bad shaped mesh elements may also cause oscillations.[/li]
[li]Decreasing the error tolerance and/or switching from the default euclidian L2 integeral (RMS) norm to the maximum error norm may decrease the imbalance [/li]
[li]You may try to use the fully implicit FE/BE predictor corrector scheme[/li]
[li]You may try to use the PARDISO equation solver[/li]
[/list]

Thanks for the note Adam. I think the FEFLOW Support has to look at it. Could you please contact the FEFLOW Support? https://www.mikepoweredbydhi.com/support

The Data panel has the option to show the Darcy flux as a scalar quantity (velocity). Using the elemental option of the parameter, the velocities calculated for each mesh element are shown as discontinuous velocity field.

Your question seems to be data specific. I suggest to contact the FEFLOW Support? https://www.mikepoweredbydhi.com/support

If you assign the Cauchy BC vertically throughout the layers, the cross-sectional area is automatically calculated by the lengths (along the trace of the river) multiplied with the saturated thickness.

Yes, that's in discussion. A decision has not been done yet. Anyway, the creation of the mesh is a good step in this direction and adding manually or automatically scalar or vecor quanitities to an existing mesh is easier than creating the mesh.

The top and bottom lines are represented by add-ins of the Supermesh, while the dat-file contains points for the whole fault area.

You have to export a selection to VTU. Go to the [b]Selection Panel[/b] and right-click on a selection of interest. Choose [b]Export[/b] from the context menu. Please note that the current implementation exports geometrical items of the mesh only. Scalar or vector quantities are not supported yet. As a workaround, you may export the mesh as an ASCII based file and modify the file with scalar quantities (e.g. mass concentrations) you previously exported into another file your you previously retrieved via the FEFLOW API (C/C++/Python).

The dat-file contains elevations to be interpolated on the slice to represent an inclined fault. The file has the followin structure:
