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.
