How to find elements which nearest slice-1?

I want to set a different conductivity(Kxx) in a vertical range(depth).

ex: Let the depth 100m-160m be a region which's conductivity are 1e-4.

And the output Kxx data from FEFLOW is element data.

but the region depth 100m-160m need to subtract "dem"(Digital Elevation Model) firstly.

So, I need to find all the elements which nearest slice-1, and use these elements's elevation(center Z) to subtract "dem".

then can correctly define the vertical range.

Hi Jimmy,

If you like to assign different Kxx based on elevation/depth, you can simply do it by using expression formula.

You can also select elements in a specific slice by clicking select all in slice view.

Hope it helps!

Best,
James

The latest FEFLOW 7.4 includes a nodal parameter (Auxiliary data) named "Nodal depth". Such as parameter uses as reference the elevation of Slice 1 to compute the depth. You can easily use the information in any expression as commented above.
