User defined result to find safety factor with beams

Hello all,

I am attempting to create a user defined result to calculate the safety factor of my beam-modeled chassis. I have done the following:

  1. Successfully solved my model
  2. Evaluated the Maximum Combined Stress for my model
  3. Found the code for Maximum Combined Stress (BEANMAX_COMBINED) in the solution worksheet
  4. I found the yield strength of material I am using, which is 250 MPa.
  5. I created a user defined result that with the following parameters:

However I get positive and negative infinities:

And a warning that this result could not be evaluated over all bodies.

I can obviously hand calculate the FOS, but I want the result for each member in particular.

Where is the error in my procedure?

Thank you!
