Hi! I’m wondering if the multi-configuration operand PRAM will work with Non-sequential mode. There are only 3 surfaces available in the Properties menu for the operand, and NSC mode doesn’t use surfaces (just objects), so this may be a clue. I am trying to configure a model where the “Minimum X Half Width” parameter from an Annulus object changes from 15 to 30. PRAM may not be the operand to use, but I do not know what else would work. 

Once these two configurations are set, I’d like to run a ray trace to see the results for both scenarios on the detector surface behind the Annulus object. 

Any suggestions for how to go about this are welcome. 

Thank you!
