Dear E+ Users,
I have a question regarding boundary conditions „Zone“ and „Surface“.
Attached you’ll find two nearly identical models. The only difference is the boundary condition.
I thought that defining “Zone” as a boundary condition would give the same results as setting it to “Surface”.
Fact is that it doesn’t.
I found in the I/O reference that when defining “Zone” as the boundary condition, E+ creates an equivalent surface to the defined surface.
Is my assumption correct that when I draw 2 zones and connect them using the “Zone” condition, that I would get 4 surfaces which are considered in the simulations?
Therefore the transmission gains/losses would be overrated.
Thanks for your thoughts and help.
LG, Florian
