Very Dense mesh from Butterfly sample file

[MarZan]

Hello, I’m just getting into Butterfly, and I can’t seem to figure out why my mesh is more detailed/heavy than what is shown in this tutorial (https://www.youtube.com/watch?v=0auA5exoL9M&t=917s)

I’m using the example file: 01_0_outdoor_airflow.gh
I haven’t changed any of the settings besides toggling true the [wind tunnel], [grading], [blockmesh], and lastly [visualize mesh].

When I toggle true the visualize mesh, its so large it sometimes causes grasshopper to crash.

Is there a reason why my mesh is so dense?

@MarZan The mesh of your model is quite normal. Because the video (https://www.youtube.com/watch?v=0auA5exoL9M&t=917s)created by @mostapha is used butterfly Version 0.0.04. In the new butterfly version 0.0.05 , it has a new compotent called wind tunnel grading.This compotent maked the difference, you should pay more attention on this compotent.
