I have loads of top of earth berm and need to check the stability of the slope (see attached). Can I use this software for that? Thanks,

If not, can someone link me to a calculation sample how to do this?
I have not done slope stability before. This is just one time thing, we just need to check it's ok to put a crane on top of berm. Berm is clay material with crush rock on the surface of the slope.

it's a class geotechnical problem that can be solved by any FEM/FDM programs including ADONIS. I'm afraid little bit of numerical simulation background is required though.
