I have several questions related to the CFD simulation of a multi zone space. I have to reference here an earlier topic called “multi zone” posted on this forum in December 2011. That topic ended up with a post/instruction comprising a series of steps that I have strictly followed but I still experience the same problem stated in that topic, so definitely solution is not that simple.
I started modelling of a multistorey atrium space (room no.1) with four rooms (stories) (rooms no. 2, 3, 4 and 5.) adjacent to the atrium and open towards atrium, similar to the visualization illustration example in the Micro Flo User Guide. I ran the Apache simulation. In the CFD module I took room no. 1 (atrium) as a parent room and I created multi zone space by adding rooms 2, 3, 4 and 5. Then, I created multi-zone space partitions, imported boundary conditions from Vista and ran CFD simulation. I was surprised with what I got: the velocity vectors visualization showed that CFD didn’t recognized floors/ceilings between rooms 2&3, 3&4 and between 4&5, while partial vertical partitions from rooms 2, 3, 4 and 5 towards atrium were recognized.
Does anybody have explanation for this? I’m wondering whether I did something wrong or this is a kind of limitation of CFD module dealing with multi-zone space? Does ApacheSim recognize those ceilings/floors?
