There are two basic strategies for the definition of initial hydraulic heads for transient simulations:

[b]1. Interpolation from observations[/b]
If a large number of observations is available for the starting time of the model and the observations sufficiently cover the entire model domain (both horizontally and overlying aquifers), the initial conditions can be derived from the observed hydraulic heads by interpolation.

[b]2. Results of a steady-state simulation[/b]
In case that not enough observations are available for direct interpolation, initial hydraulic heads can be obtained from a steady-state simulation. As the hydraulic-head distribution in this case reflects average conditions, the model might need a starting period to adapt to actual conditions before producing reliable results.

For me it seems available data for the initial condition are rather sparse. Accordingly, the second option might be usefull. If you still want to use the first option you may try to regionalize the data by means of a parameter link.

The introductory tutorial, page 34 shows you one possible workflow.

You also contacted the FEFLOW Support. The support provided you an answer via e-mail.

The recent implementation shows you the labels of the histories. A legend is not supported. Accordingly, you need to visualize the histories externally.

In my point of view, the best starting point is to go through our Introductory Tutorial. This tutorial nicely guides you step-by-step through the FEFLOW GUI and shows you the conceptual framework. After you went through the exercise, you could start with the cross-section model you are interested in. I am sure the short time you invest in doing the tutorial make many steps your following project easier. Please find the Introductory Tutorial here:

The vertices of a polygon are counted counter clock-wise. The orientation of the vertices which are shared by the inner and by the outer polygon are clockwise. This is not supported by FEFLOW. Instead, the vertices must be counter-clockwise. You need a GIS tool which allows you to change the order of the vertices.

Which Boundary Condition (BC) did you assign at the surface?

I would not exclude that recovering is possible. However, re-running the model is the easier and faster way. If you re-run the model, please assure you have enough space on your hard disc. Incomplete files are usually caused by insufficient disc space.

I would need more details about the model to find an explanation. I suggest to contact the FEFLOW Support: https://www.mikepoweredbydhi.com/support

If you want to work with 2D or 3D layered-based meshes, the feature you are looking for still does not exist. However, the feature is available if you are interested in going for partially- or fully-unstructured meshes. You can re-mesh your model domain or parts of the model domain and include Addins to constrain the mesh generator TetGen to locate mesh nodes on the locations you are interested in.
