Eddy3D- Bounding Box domain not generating

I am trying to run the simulation for Wind analysis and insert the Terrance surface and the Building geometry separately. But for some reason, the Bounding box domain isn’t generating the Wind Tunnel Volume for me.

This is resulting in incorrect Results! @eddy3d , Any solution I get here
