Hi,
It is possible to add divalent ions using tleap.
Page 50 of the Amber 17 manual includes section 3.6, "Ions" which specifies
the parameters available.
Divalent ions are loaded for the specific water model used (specified in
leaprc.water.????), and the default parameters are reported in:
Li, P.; Roberts, B.P.; Chakravorty, D.K.; Merz, K.M. Jr. Rational Design
of Particle Mesh Ewald Compatible Lennard-Jones Parameters for +2 Metal
Cations in Explicit Solvent. J. Chem. Theory Comput., 2013, 9, 2733–2748. 20
