Hello,
I am an architecture student, and I am working on a passive cooling, naturally ventilated design. I am still a beginner with Simulation CFD. I was trying to see what my options are with my project. I basically want to simulate how the air enters the room from the outside, how it moves inside and how the temperature changes. I know it sounds pretty simple. Are there any videos or tutorials to help with that? Question 2, does Simulation CFD use weather files or do I always have to specify the weather conditions and so.
Hi,
I have just shared a Dropbox folder with you, please place the CFZ file in there - the invite will come from my personal email just FYI.
Kind regards,
Jon
Morning,
Just so you are aware, the Dropbox folder is still empty, did you copy the file over?
Kind regards,
Jon
Thanks for sharing the file, I have a few comments:
Take a close look at the geometry here, it does not look like I would expect, it is not smooth - this is beneath one of the curved 'lids'
We also have an infinitely small angle beneath the persons legs where they meet the chair, this ought to be square to prevent the mesher from struggling
I hope these points help. Sorry I cannot get it running right away. I tried a manual mesh also which often circumvents some geometry issues but not with this model.
Kind regards,
Jon
Hello John,
I have 2 queries related to natural ventilation applications where the surrounding environment is modeled:
1. will the CF heat transfer coefficients imposed at the walls be calculated automatically (considering the wall thickness and conductivity)?
2. Is it possible to assign velocity boundary condition with vectors which are not perpendicular to the inlet surface?
Thanks and best regards

Hi W.Mousa,
Thanks for reaching out to Autodesk community 🙂
May I ask that you open a new thread for your questions.
We would be glad to assist you from there 🙂
Thanks for your understanding!
Will wait for your new thread,
Thanks,
Amal
