Wind result with non smooth edge - refinement

Hi all,

I ran a wind study while the result showed some non smooth edges at each block.
Would anyone please advise some ways to solve it?

I would look at meshing density. Please generte a gradient mesh using Butterfly_Grading_XYZ component.

@Ivanna I have met the same question. Please refer to this link.

Hi, have read your post before, but there is no Nov 2017 version 4. The one available for dl is just Mar 2017 version 4. Can you share the updated files to me so that I can updated my butterfly without upgrading to version 5.

And also curious if anyone can solve the issue with old version?

@Ivanna Butterfly 0.0.05 added a new component call wind tunnel grading. This compotent solved my question about more smooth result. I suggest you to add it to your workflow.
