Dear Sirs,<div><br></div><div>I model a multi-zone building and there are two adjacent zones which do not have inter-zonal wall between them, because of the geometry and the orientation I decided not to model them as one zone. How can I assign the lack of inter-zonal wall, is it enough if I set an air layer as the only wall's material? Do I have to assign any other parameter in order to be more accurate?</div>
<div>Thank you.</div><div><br></div><div>Regards,</div><div>Eva</div>
