FEFLOW 7.0 Anisotropy - rotation angle

Dear FEFLOW Community.

I`m thankful for the technical support of the FEFLOW community.

I have a question with regard to the rotation angle due to the 2D anisotropic conductivity (measured in 2 directions: 0 deg and 90 deg).
I handle with a compacted and layered landfill capping System with specific slope, that was determined from the geometry data.
Can I use the slope of the geometry as rotation angle (anisotropy angle)? or how can I determine the rotation angle depending on kmax and kmin?

Best regards.

FEFLOW has the capability to automatically compute anisotropy angles based on the slope of each element. This method is listed as [b]General anisotropy with computed angles[/b] in the [b]Problem Settings[/b].
