Obviously it goes without saying that boundary conditions are very important here. We have open foam as well but haven't carried out nat vent designs in it yet. </div><div><br></div><div>Similarly to IES the offering from Designbuilder is a good tool which we have used a number of times for such buildings. It uses the energyplus simulation engine and the results of your simulation can be linked to the CFD model. </div><div><br></div><div>I am due to give a webinar on the 23 march on it's use for this purpose and I would suggest it might be useful for you to register for it. I believe further details are available on the designbuilder website (<a href="http://www.DesignBuilder.co.uk">www.DesignBuilder.co.uk</a>). This software is very competetively priced and has a very intuitive GUI & modelling process.</div><div><br></div><div>ESPr might offer another option but I can't offer any advice on it's Cfd capabilities though I do believe it has them albeit fairly crude. It's thermal modelling engine is open source and it has some advanced modelling capabilities beyond many commercial tools. It's user interface is in my own opinion quite hard to use. But if you are happy with nist and openfoam my guess us that text based modelling doesn't phase you. </div><div><br></div><div>Hope this is helpful. </div><div><br></div><div>Kind Regards</div><div>Paul</div><div><br></div><div>Dr Paul Carey</div><div>Director</div><div><br></div><div>Zero Energy Design Ltd</div><div><a href="http://Www.zed-UK.com">Www.zed-UK.com</a></div><div> </div><div><br></div><div> </div><div><br></div><div> </div><div><br></div><div> </div><div><br></div><div><br></div><div><br></div><div> </div><div><br>Sent from my iPhone</div><div><br>On 1 Mar 2010, at 20:17, <a href="mailto:Shariq_Ali@URSCorp.com">Shariq_Ali@URSCorp.com</a> wrote:<br><br></div><div></div><blockquote type="cite"><div>
