I made a fourth-order pass-through filter, when the width of the coupling window in the middle of the second and third cavities is 2.398mm, it is displayed normally, as shown in Fig. 1, but when I change it to 2.397mm, the metallization holes are all gone, and there is an error message, as shown in Fig. 2 and 3. Anyone know what the reason is, thanks!

This seems to be a parametrization error from your side. Make sure that the parameters make sense for the geometry modeler.
