Hi.

I'm new in openFoam and I'm interesting in doing a simulation where wind outside of a building get in at the build and disperse fibers. The fibers can disperse inside of the building or move through windows or doors or whatever to get out of the building.

There are a lot of solvers for this and I would like you recommend any for this. Also I have to mention that there is no a great difference between a gas and the fibers, because this fibers are really volatiles and it's no necessary for me to represent deposition or any reaction, I just want to represent convection and diffusion. The solver should let represent RANS or LES model.

Thank you so much for your attention.

check the multiphase solvers:
twophaseeulerfoam, multiphaseeulerfoam,
reactingtwophaseeulerfoam, reactingmultiphaseeulerfoam

read the descriptions on the website for those solvers.

You can also try scalarTransportFoam to do a quick simulation.

I usually use reactingtwophaseeulerfoam as it is very convenient. But recently, I began to think about what would happen if the air weren’t so badly polluted. Why are so few people trying to solve this problem? As everyone knows - if you want to solve some kind of problem, then you need to start with yourself, which I did. I started caring for nature using the phone app from Carbon Click. In it, I receive daily small tasks to improve nature. I think that if every person begins to help nature, then a huge number of problems can be avoided.

Hi Guys.

Is it correct to use Volume Of Fluid Method (VOF) to take alpha.air as concentration?
What do you think about it?

Thanks.
