This is more of a general question for best practices and/or any specific techniques for simulating wind in an urban setting with “hilly” topography.
We are performing pedestrian comfort analysis for a residential project with fairly hilly topography on the site.
My understanding is that such models need to be simulated in wind tunnel setting and wind tunnel requires a windward and leeward buffer space.
If we model a topography pedestal (example sketch below), will that have any unnecessary turbulence in the simulation? See red and orange lines in the image. I am doing the analysis for the blue highlighted space.
If the answer to question 1 is yes, what can I do to avoid that? Should I input 0 as a multiplier for windward in the Butterfly_wind_tunnel_parameters component? Does that skew the results in any undesirable way?
Is there any documentation or resource I can refer for general best practices for various corner cases?
