Only one CFD zone is possible.<o:p></o:p><o:p> </o:p>Yes, you can add "blockages", e.g. "furniture" or "half height walls". However, these cannot be coupled to thermal properties (hot wall or such like) to my knowledge. They are flow barriers, only.<o:p></o:p><o:p> </o:p>You can couple the CFD zone with an air flow network. I do not quite understand your first question, but if it is an array of air outlets exhausting air into a larger void (atrium or some such space), then this should be possible via CFD in the large zone and afn for the air exhausts.<o:p></o:p><o:p> </o:p>Best<o:p></o:p>Achim<o:p></o:p><o:p> </o:p><o:p> </o:p><div style='border:none;border-left:solid blue 1.5pt;padding:0cm 0cm 0cm 4.0pt'><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'>Von: esp-r-bounces@lists.strath.ac.uk [mailto:esp-r-bounces@lists.strath.ac.uk] Im Auftrag von Matthew Wright Gesendet: Donnerstag, 20.

It’s a typical air flow through small opening problem.<o:p></o:p><o:p> </o:p>In short, does the CFD only model a clear rectangular space, or can physical walls or nominal thickness be inserted into the airflow?<o:p></o:p>IF it only models clear spaces, is it possible to run several spaces connected via a flow network or some sort to simulate the physics properly?<o:p></o:p><o:p> </o:p>Thank you for any information.<o:p></o:p><o:p> </o:p>Regards<o:p></o:p> <o:p></o:p>Matt<o:p></o:p>Matthew Wright MA Physics (Oxon) PGCE<o:p></o:p>Physicist<o:p></o:p> <o:p></o:p>e: <a href="mailto:Matthew.Wright@c4ci.eu">Matthew.Wright@c4ci.eu</a><o:p></o:p>m: +44 (0)7908030742<o:p></o:p>p: +44 (0)1823 617166<o:p></o:p> <o:p></o:p>P Please think before you print !<o:p></o:p><img border=0 width=268 height=104 id="Picture_x0020_1" src="cid:image001.jpg@01CDDF55.4D7B68C0" alt="c4ci logo 4-v2"> This e-mail including attachments is confidential, may be covered by legal professional privilege and is intended for the addressee only.
