Hi Thomas,

I have installed today OF 2.3.
Can you upload your file again please ?


This one :

[EDIT] I upload the case again:

I will tell you if it works fine with OF 2.3 on my computer.
Thanks a lot.
Regards,
Mat

hi dear
i want to simulate a similar case
but i cant download that page
can you get me or uploat it again
thanks

Hi

I am also looking to access the tutorial for the buoyantBoussinesqSimpleFoam solver - I believe this is solver for the case I need to run (see attached)

attached is a picture of the model and domain, I have divided the boundary patches into torso, head, left arm, left forearm, left thigh, left leg and left foot (the same for the right) - in order to assign thermal boundary conditions for each in order to develop a better understanding into thermal comfort.
- I am relatively new to opensoure software and would be most grateful for any pointers in the right direction - I have yet to export the case into openFoam from engrid.

You are on the right track. I've picked the right solver.
It is hard to direct you without knowing what you want to achieve and without knowing what kind of info would be helpfull to have.

Try to have some questions if you want to have answers. The more specific you are, the more precise we will be

Hi
My case may be similar to the one in this thread - I intend to conduct a thermal analysis on the human body within a cube domain with overhead inlet and outlet points over head - I am using the hotroom tutorial for guidance but have issues with the nut file - I receive a fatal error - I am wondering if you could share the case file for the natural ventilation with open windows to guide me - attached are images of the domain and model so you can get a feel for the problem - I eventually intend to impose heat flux boundary conditions on parts of the human body.
I would be grateful for assistance - the model works in paraView and the 0 case directory seems to be fine apart from the nut file where I receive an error
--FOAM FATAL ERROR:
Attempt to return primitive entry IT stream.......
primitiveEntry "outlet" comprises
on line 60 the word 'type'
on line 60 the word 'fixedValue'
as a sub dictionary

relatively new to openFoam and would appreciate a look at your 0 case file for natural convection case
kind regards

Hi,

you should share your 0 Folder at least. So we can have a look on it.

Bye

Hi
thanks for the response
attached is a link for my zero directory:
https://www.dropbox.com/sh/8pqnphv42...eKloQauJkuy0ba
the solution blows up after a several minutes - I can not work out what the problem could be - I would be most grateful if you could have a look - I am desperately trying to find other boussinesq examples for guidance.
the case is for a human body within a cube domain with inlet and outlet points overhead.
kind regards

Hi everybody, I post here because my case is similar.
I need to roughly model a ship engine room to check the efficiency of a mechanical ventilation system. I'd like to start from a simpler case, e.g. a cubic room with an inlet and outlet hole on two different walls. Please, have you samples or tutorials for that? Thanks for your attention.

Hi Vaina74

I managed to successfully complete my project on thermal comfort, where I utilised Blender, enGrid and OpenFoam to evaluate thermal comfort of seated occupants within a modified cubed domain with overhead inlet and outlet to represent an enclosed cabin environment. If you like I can share a PDF file of the masters thesis where a methodology is presented - hopefully you can use it as a guide for running your own case.
kind regards
g

Dear Gowain, thanks for your quick reply. Good to hear about your project, I will be grateful if you would like to share your work as a starting point.

[eaglemckenna]

Vaina74 see the following link - hopefully the methodology should help you.

[vaina74]

Thanks, Gowain. I have just downloaded your thesis and at a first look it will be very useful. I will provide a feedback

[wc34071209]

this thread seems to be very informative. thank evrrybody here.

[wc34071209]

Hi Gowain,

where did you get 'comfortFoam' which you used in your thesis?

by the way, the link Tomas provided is not valid any more. could you please share it again if you have a copy?

[behrouz]

hi to all
i am started linux and openfoam a few weeks ago and i am such a beginner so
i try to simulate a simple ventilation case,like a simple room with 2 or 3 person in it and common load like radition and etc with one indoor supply air.wich one of case in tutorials i should use?and how can i run it?
any refrence,guid or idea and... can help
tnx

Hi, mathieu
Have you solved this problem? I encountered the same problem
I use foam-extend3.1 version
Can you give me some suggestion?

Best Regards,
Aaron

Hi Tian,

Would it be possible to get ahold of this case you had uploaded? I think the link is now broken.

I'm working on a case of single sided ventilation in a room with heat transfer, meaning the air can come in and out from the same opening. The heat stratifies and stacks until it flows out from the top of the opening, allowing cooler air to come in from the bottom.

Would you be able to recommend suitable BC for U, p, p_rgh, k, epsilon, ?
i'll add radiation as with buoyantPimpleFoam once the BC are sorted.

Thanks in advance,

Best
Olivier

It used buoyantBoussinesqSimpleFoam with k-Omega SST and radiations

Hi,

if you can share your 3D Model than I can try to set up an example for you.

Dear Matthieu and Dear Tian,

Firstly, I would like to say hello to you. I would like to wish you best wishes and good health in the covid-19 pandemic.

Secondly, I am a newbie (OpenFOAM). Now, I am also using OpenFOAM to simulate natural ventilation on buildings. Previously, I used Fluent to simulate airflow but because of the cost of the license, I must be used OpenFOAM. So I would like to contact you, Could I contact you via email to learn about OpenFOAM and discuss it with you? Could give me your email address?

Thank you so much
