HFSS: What on my model is generating this warning?

I designed a model of a patch antenna with circular polarization, but I keep getting this warning when I run the analysis:

Model Resolution has caused minor changes in object dimensions or contact between objects. Specific details may be found in Modeler>Model Analysis>Show Analysis Dialog>Last Simulation Mesh.

The simulation gets complete, even with this warning.

What can I make to avoid this warning?

The project file is ATTACHED to this message

Hi fernandojsm,

I wasn't able to find anything particularly incorrect. It looks like most of your units are in meters; try changing them to mm and see if that helps.

Thanks for your reply PlanarMaterias,
Just changed all of my local variables to meter in [HFSS->Design Properties]; then changed the project units to mm [Modeler->Units]; then returned to meter [Modeler->Units]. Now the warning is gone!
