Hello. I met with a problem when I use AFN mode in Archsim. I wanted to simulate and compare the thermal characteristic of a cavity in a double skin facade (DSF) with different design parameters. But I find it seems impossible to create a horizontal opening as the lower vent installed in the DSF, which would cause a severe error said “The horizontal opening must be located between two thermal zones”. (Like the attached picture shows, picture from )
Therefore, I’d like to know is there any way that can help me to build a horizontal opening exposed to outdoors? It’s very important to my simulation.
Thanks for your kind help. Look forward to your reply.
