Hey. Ive been trying to implement a 2d vawt case using overset meshes. Ive been having issues with the interpolation at the fringe. Looking at the velocity field, I see some timesteps with a noticeable interpolation error between the background and the component meshes. I suspect this is because the field values are changing a lot near the interpolation fringe ( and that is generally not recommended?). I cant make the component meshes much larger to prevent this issue because then the component mesh goes outside the background mesh region. I attached photos of the component vs background mesh so you all could check if the mesh resolution is the one that's causing the issue. That is one thing I need help with. Secondly, the pressure field is all over the place: spurious oscillations and unresolved features. Could someone go over my case files and see if am making any mistakes while setting up the case/ better controls?
