Dear Sue,

the "bad atom type" message indeed comes from the parameter assignment
for SA calculations within mdread.f (and the "... undefined value ..."
is a follow up then). You might have a look at the section for Mg ions
there as a starting point to extend the code for your purposes.

Best regards

Holger
