I want to run a wind analysis at the urban scale ( I saw some of you who tried @devang, @minggangyin, @TheodorosGalanos,). Despite my research on the forum and on github where I found some snippets of informations, I didn’t saw enough to significantly help through that journey…
What kind of settings are preferable for the grading part and for snappyhexmesh at that scale ?
Maybe you have a template with basic settings for this kind of analysis that you may want to share ?
As you can see in the definition I started, the refinement region is not align with the case (windtunnel). It doesn’t seem optimal. Is that important ? As I want to analyse the wind in few directions, is it better to rotate the case ?
