Hi,
Since you are using a custom non-uniform mesh, you can change the mesh density by changing the number of mesh cells per wavelength.
Increasing the mesh will make the mesh denser. So, you will use this as the parameter for the sweep. For the result, you can use any result that maybe of interest to you. For example, you can check how the transmission or the reflection changes for different mesh accuracy. With increasing mech accuracy, they should look similar, which gives us more confidence on the results.Â
I saw Guilin's post. I will ask him about the first link. Would you be able to share a screenshot of your result (without convergence testing)? You need to reduce the auto shutoff typically only when you see oscillations in the transmission/reflection spectrum. Otherwise the default levels are good enough. I don't think it is an issue if the auto shutoff falls too quickly if you don't see any oscilations in the data.
