Ignoring or excluding mesh in some regions while being able to simulate

I wanted to ask if it is possible to exclude some regions when modeling the mesh for a large or complex system.

For example, modeling a micro antenna with centimeter-size wires is too dense a mesh to model. Along with the air region around.

So i wanted to see if one could ignore some regions that are unimportant, so as to save space and time, whilst still simulating somehow.

Maybe look into virtual operations.

For many antenna problems the interior of conductors can be excluded from the simulation and the impedance boundary condition applied on the conductor surfaces.
