Digital twins of office equipment - part 2 

Thanks for the question. At its current level of complexity and with only a few of these in an office building would have a minimal impact on run time. If the building hosted scores of these for production work then scaling would be an issue - one would likely need to setup lots of different work loads and the host room would certainly grow in complexity (with the shared surfaces) and that could test a solver. The shorter tilmestep is the elephant in the room. It will create larger performance results files as well as longer to run-times. It would be worth testing to see if a 2 or 3 minute tilmestep degrades the deliverables. I would make a differently complex model if it were being made for use by the mfg of the kit who wanted to study heat transfer within the machine. That would be multi-zone and might require an order of magnitude more surfaces as well as that destructive tear-apart and lots more monitoring. And if one were serious about run-time creating an even more abstract variant would be worth trying. If a detailed comfort study was not called for a more abstract DT might be good enough.
