How to create an output expression for given expression using aged and fresh results

noramirkh

Dear Support,

I am running Aging simulation using ADE Assembler and want to create an expression, which represents difference of 10yr and stress or fresh results. I am interested in difference between aged and fresh results for all my output expressions. How can I easily have results table wit those differences. 

Any hints how I can achieve that?

    You can do this using the new calcValForRel function which was added in IC618/ICADVM181 ISR7. This allows you to reference the value of an output at a particular age and then build another expression which then uses that - so it could take the difference between the aged and the fresh, for example.

    Regards,

    Andrew.

    Hi Andrew,

    Thanks for quick response.

    Here is my version. Isn't it the latest one? 

    I am not able to see that function:

    Unfortunately not. That's ISR2 (the 500.2 on the end indicates this; you'd need to use at least 500.7 which is a later hotfix). Even then calcValForRel doesn't show up in the expression builder - you'd just need to type it in with the right arguments. You can find it by typing startFinder() in the CIW and searching for calcValForRel and then hitting the more info button (this too would require ISR7 or later). It mostly shares the same arguments as calcVal with some extra to enable the aging information.

    CCR 2158785 is to get it supported in the expression builder (which will make it easier, of course).
