You can use CFD0 incorporated into the CFD0Editor to generate wind pressure coefficient profiles for your specific building geometry.<br>
Please see the following web page for the <i>Coupled Multizone-CFD Tutorial </i>which provides a link to a zip file that contains a
<i>CONTAM-30-Tutorial.pdf</i> and files required to run the example cases. <a href="https://www.nist.gov/el/energy-and-environment-division-73200/nist-multizone-modeling/software-tools/contam/tutorials">

<p class="MsoNormal">I would also love to know. I've been pushing for DesignBuilder to incorporate this into their external CFD Model so I can transfer the boundary conditions easily to e+. I've been waiting 7 years at least. Till now, I've been using the algorithm
in e+ AFN modules, but it's not ideal. I have to manually tweak for courtyards, and so on.<o:p></o:p></p>

<p>Colleagues, <o:p></o:p></p>
<p> Does anyone have any suggestions for tools to help with generating wind pressure coefficient values for buildings? I used to use CpGenerator and was very happy with its results. Sadly, it is no longer available. CPCALC is a little rough around the edges
and I do not have project time or budget to get Cp values by testing. I imagine that the values can be generated by CFD analysis but I have no direct experience in that regard. I am interested to know whether people have found cost effective ways of generating
Cp values.<o:p></o:p></p>
<p>I hope everyone is staying healthy!<o:p></o:p></p>
