This issue has come up several times on the list (see e.g.
http://archive.ambermd.org/201204/0666.html etc). You need to load an
ion parameter set prior to adding ions. For example, to load the Joung
& Cheatham ion parameters for TIP3P:
loadamberparams frcmod.ionsjc_tip3p
See section 2.9 (Ions) of the AmberTools 13 manual for further details.
Hope this helps,
