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:
- Successfully solved my model
- Evaluated the Maximum Combined Stress for my model
- Found the code for Maximum Combined Stress (BEANMAX_COMBINED) in the solution worksheet
- I found the yield strength of material I am using, which is 250 MPa.
- 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!

Hi @Gotta_Go_Fast ,
I think your data in BEANMAX_COMBINED contains a zero value and that is causing the error. You can calculate 1/ FoS.
