I've posted previously on other forums and haven't had any success finding my answer. I'm trying again.
Let me summarize what I'm looking for.
I’m looking for a way to get the architectural/structural model geometry exported from Revit to use in a 3rd party CFD (computational fluid dynamics) simulation program. I need a good process for creating a “negative volume” solid extract of a Revit model. This means essentially a “solid” mold of the air-only region inside a structure.
If I understand it correctly, Autodesk CFD will create this volume. I however, need to create the volume first, in order to import it into the CFD program I'm using (Simscale).
I've attached three different .rvt files that I've been using to try and troubleshoot the issue, even though most geometries I'll be working with on a daily basis will be much more complicated. One file is a very simple file with the air inlets and large vehicle opening (in the exterior walls) and the air outlets (centered in the interior) as openings in the walls. The second file is exactly the same with the openings filled in. The third is a more complex geometry that I would expect to see on a daily basis from my structural/architectural engineering team.
Any input here would be greatly appreciated!
Thanks in advance,
Justin
Hi @Anonymous
Which version of Revit are you using?
Have you created the architectural/structural model geometry in Revit or this is an import from another program?

I use either Revit 2016, 2017 or 2018 at the moment. The fiels I previously attached were created in Revit 2017. The structural model was created in Revit, not imported from another program. Thanks!
Hi @Anonymous
Thanks for responding!
We will test the files with Revit 2017. I will try to get some input from a CFD specialist on this.
Meanwhile, can you confirm if you are on the latest build of Revit 2017?

I'm using Revit 2017.2.3.
@Viveka_CD, I've been working with CFD specialist @Jon.Wilde.

That's awesome. Good to know you have a CFD specialist already on this one.
Do you have a case number that I can add the updates?

I do not have a case number, I've just been using forum posts. I added you to a post that so far includes input from @Jon.Wilde and @matt.bemis. Thank you all for your help!
Hi @Anonymous
Thanks for connecting the threads and adding me to the CFD discussion
This thread has more details which will help with the testing.

Thank you @Viveka_CD! I will read all of the information you provided and get back to you if this is a solution. In the meantime, it appears the link you provided for "different methods for improving your products and fluid flow performance in simulation CFD", may not be correct.
Thanks again,
Justin
Hi @Anonymous
Thanks for the heads-up!
I've updated the link.
Let me know how it goes and I look forward to hearing from you.
