Hi,

I'm trying to run a design study and want to ensure there is a minum factor of safety, however I can't seem to get the FOS sensor to work.  I am adding it by right clicking on the sensors folder > add sensor > simulation data, leaving data quantitiy as stress and putting a check in the FOS box and the only option available is "Use limit strength in material data".  Is this the correct process?

After running the simulation, my displacement sensor updates to the correct value, however the Factor of Safety sensor remains unchanged, just stating "Data not available".  I know from creating a FOS plot in the results that the FOS is 2.2, but why isn't the sensor showing this?  The problem is that I can't use that sensor in the design study as it either shows the displacement factor of safety or the stress as a value or just 0.

Any advice would be greatly appreciated!
