I am trying to simulate wind flow around a tall building. My problem might seem very easy to solve for someone. I am getting unexpected high wind velocity and also it seems like wind is not flowing straight from the velocity input surface. I have used enclosure function to have wind tunnel condition. Please see the attached images for more details
Can anyone suggest me what is the problem here?
Please always share your project with us, it does not have to be the velocity BC itself that causes that issue. Need to have a look at the other BCs as well (alternatively also numerical settings).
I had a look in your public projects to find the link (I’ll post it here if anyone else is interested SimScale)
I’ve seen this kind of issue happening with quite a lot of users recently. Usually enabling “potential foam initialization” under “simulation control” is enough to solve this problem. Can you give it a go and report here?
By the way, I believe the “roof” boundary condition should be slip.
Thanks @jousefm, looks like someone else has already provided the link for me. But thanks for your suggestion, I will provide a link from now on if I face any problem
Thansk a lot @Ricardopg. This simple step has solved the complete wind flow. I was facing this problem from day one. Below is some screenshots with the results after checking on Potential foam initialization

Again, thanks a lot
