HB PMV Comfort Map - Testing Radiant Mechanical Systems

Hi @chris
re-opening this topic and referencing the suggestion on this forum post:

Adding heat sources to outdoor comfort model

Hey @joshkpeterson It’s clear you’ve done a bunch of research, and it seems a lot of folks are interested and puzzled by your question too. I think @dmitry dmitry’s suggestion and conclusion is spot on. As of now, none of the components in Ladybug Tools can efficiently calculate the outdoor air temperature via convection (Butterfly can do some of this, but the complexity of outdoor thermal environments is still too much for Butterfly’s current capabilities). However, if you’re looking to add…

I am conducting a study that looks at an atrium space that is 40m high, used the Airflow Network to model the atrium space as it gave a much better distribution of temperatures throughout the atrium height. I’m trying now to understand the impact of radiant surface on the Longwave MRT / Comfort within different heights of the space… Figured that the approach of HB Other Side Temperature mentioned here would better fit the story I’m after.

I used the AFN file example to replicate the error, it appears is that the AFN model does not like the addition of the room added that represents the radiant surfaces:

If I try to bypass the HB AFN component, the simulation runs fine:

however, when using the AFN, the following error apears:

would appreciate if you could point out what might be causing the issue!
