We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

It will; the IF statement means that as soon as the PCM < 514K 20,000 W/m2 is applies, as soon as it is over 514K the other flux applies. It's not a IF then stay effect. You may be able to use the equivalent of the Expression in a UDF with nested IFs? You'll need another condition to retain one or other of the wall states until something else happens. 

Nice idea, I'd not thought of that, and wouldn't have been able to suggest it either.Â
