hfss design error-mesh matching process failed

hi,
while analysing the design in hfss, i get an error "mesh matching process failed" how can i solve it?
thank you.

Are you using master/slave boundaries?

Maybe there are some solids oversubscribing each other, or a ***** somewhere.

Hello PlanarMetamaterials
I have the same problem and indeed I am using Master/Slave BC in HFSS with array tool. Do you know what the problem and how I could overcome it?

Generally, this means that the structure is not identical on both mater and slave boundaries. Ensure that both surfaces overlap with exactly the same physical setup.
