BF outdoor AirFlow can't consider obstacle

Hello Guys
I model a simple outdoor airflow in BF with some open obstacle (they are not as close brep)
as a wall boundary:

but as you can see in the below pic it looks like BF can’t consider them and the result is not reasonable!

  1. Please do not tag me on a generic question like this. I check the forum regularly and reply to questions that I think I can help.
  2. You should visualize the mesh and start from there. Butterfly solver (OpenFOAM) understands your model based on the mesh that is generated from the geometry and not the input geometry itself.
