Error: Negative inside convection coefft for construction ty

Post by dnelson »

I've started a new project in version 6.4.0.12 and get this error when running either ApacheSim or ASHRAE loads. I found this thread from back in 2011 on how it was fixed, but I'm having problems deleting glazing constructions.

viewtopic.php?f=263&t=2018

The construction database manager says that I have glazing constructions (among other types) that are assigned, but I do not. So it's not letting me delete them. Does anyone know of that problem as well? Thanks.

The same problem. Changing construction fixes nothing :(
