increasing the layer elevation of 1 meter

Hi everyone, I´ve got a simple question.

Supposing that I have a 3D model with 4 layers.
I have set up the elevation of the 4th layer and I want the 3rd layer to have the same elevation as the 4th but increased by 1 meter.
How can I do that?

Thanks.

In the 3D Layer Configuration, set all slices except the 3rd to 'fixed', and change the Distance from Lower Slice to 1 m (Standard user interface).  In the Classic user interface, you cannot set a distance from the slice below, just from above. Here you would have to add slice 3 from scratch, specifiying a distance from the slice below while adding the new slice. Another option would be to export all elevations from slice 4, add 1 m to all elevations externally and import them again for slice 3.

Sorry Peter I'd like to take advantage of your helpfulness and ask two other questions about the 3D layer configuration with which I am really struggling.

1) Supposing my model has 7 layers and their elevation ranges from +65 to -30 metres.
How do I set the initial 3D layer configuration?
I set all the elevation as no fixed. But I always got an error of conflict when I assign the elevation of one layer, which is then corrected and costrained within a small range, that is not the one I assigned.


2) I would like to create a layer with a costant slope of 1 degree eastward starting from a certain elevation. How would you do that?

I'd very much appreciate if you can help me on that.
Thanks.

I think I have figured out the first question, how to set up the initial 3D geometry.

But I am still struggling with the second question.


Which is the best way to create a layer with a costant slope?

There's at least two ways for this:

1. The Classic interface contains an option called 'Skew plane' to set z values. With this, elevations can be interactively input at certain locations, and FEFLOW interpolates between the points. The locations can either be defined by mouse click or by typing in their X/Y coordinates.

2. Create a simple point file externally with elevations on two sides and use it as a basis for interpolation in FEFLOW.
