Hi All,
I am working on a 3D geometry and trying to obtain eigenfrequencies and quality factor in RF module. But it seems, eventhough Comsol can find the eigenfrequencies correctly, quality factor values changes depending on the boundary conditions used. Since it is an eigenfrequency analysis, is that normal to see different quality factor values when the boundary conditions are changed? Which boundary conditions should I use?
Anyway, I've also used PML but in this case, I start getting memory error sooner or later. Is there any way tor prevent this? Actually, my geometry has a symmetry to the x-axis, so it would be great if there is such a way to set a symmetry axis and compute only one half of the geometry.
I would appreciate any help/suggestions. Thanks in advance,
Elif
