Can HFSS Display the 3-D Conformal Mesh of Tetrahedrals?

How do I display the 3-D conformal mesh of tetrahedrals in HFSS? I wasn't
able to find the command to do this. Or maybe HFSS doesn't allow you
to see the mesh? This is for a patch antenna, or a simple dipole.

Also, why doesn't HFSS put "dBi" instead of just "dB"? It's clear they
specifically mean dBi (decibels over an ideal isotropic radiator), because the simple
dipoles I have simulated, get very close to the theoretical 2.15dBi, at the maximum
gain on the edge of the dipole "donut" shape. I feel it would be better for
them to explicitly state dBi, so that no one will assume dBd, or decibels over a dipole.

Also, what is the specific difference between "gain", "realized gain", and "directivity",
when plotting the CD polar plots? Because when you express in decibels, all
three of the plots have pretty much the same values.

Thanks for any feedback!
