We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Rob,

Thank you very much for your reply.

I did not check by changing the number of iterations. However, I changed the case with low velocity (10 or 30 m/s) and the simulation gives reliable results.

I do have another question about meshing. Please advise me if I have to post it separately in another thread.

When going for a fine mesh, or increasing the domain size, I am getting the following error,

“The specified defeaturing tolerance was found to be larger than a specified size. The elements on one or more edges may be defeatured out.”

Could you please tell me how I can resolve this? Though it shows the above error, a small portion of the domain is getting meshed properly.

Please find the image below, the geometry, where the domain with airfoil is getting meshed properly, where I thought the meshing will be complex and difficult.
