Stability analysis of tailings dams using NorSand

Hi Plaxis,

I would like to run a fully coupled stress-flow analysis of the staged construction of a tailings dam using NorSand model for the mine tailings.

After the consolidation stage, how can calculate the factor of safety for the tailings dam? can I just add a safety calculation phase to calculate the Factor of Safety? If yes, which material parameter (strength) will be reduced by the strength reduction factor. I understand that it might be not possible to use NorSand with the strength reduction factor method in which the material parameter (strength) will be reduced.

Thanks
