Hi, i don't understand one of the two options for a factor of safety plot. When you choose "areas below factor of safety", you see in red where the model is in danger. This is clear.

But when I use the option "factor of safety distribution" I get an almost totally red picture, with a scale I don't understand. What am I seeing here? Why is the whole model red?

It would be great if anyone could shed some light on this, thanks!

The factor of safety distribution shows the FOS concentration so with the case of your model study those red ones has a lower FOS compared to the yellow and green color.

SO basically the factor of safety plot show the area where the material will fail which has an FOS < 1 while the FOS Distribution show the FOS of all area of the model.
