Apparently my answer didn't go through the mailing list filter ... here it
is again ...

When you ask for a printout of the electrostatic potential, sander
will automatically use the radius definition for the supported
graphics program, i.e., that of pymol. So you're not using the radii
in the prmtop file even if you set radiopt=0. This was enforced in
sander because the PB surface has to be consistent with that of pymol
for proper visualization.
I think the supported atom type for zinc should be "Zn", but not "ZN". So if
you change the "atom type" to "Zn" when you save your prmtop file, it
should work.

Of course, if you set igb=0, no pb is used, so no "pbsa.phi"
All the best,
