regular meshing
 

Hello
I have a domain with structure and wind flow that should simulate in Fluent of Workbench.
I want to mesh it, but I don't know which way can i do that i have regular meshing, with different sizing (near the structure be smaller and the distance from structure be larger) and meshing be rectangle.
thanks for helping.

post pics and give more details about model and what you want to achieve

I have domain same as picture 1, and for example i want to mesh same as picture 2. it means that over building size of meshing is small because of can see better behavior wind flow and with way far of building size of meshing can larger but meshing rectangular and regular.
Thanks for reply.
