ADD_CONSTITUENT
ADD_CONSTITUENT [phase name]*24 [constituent description]*2000 !
This keyword adds more constituents to a phase that already has some constituents. Its syntax is the same as for the CONSTITUENT keyword. This keyword can be used several times, if the phase is very large, e.g. a gaseous mixture or a complex aqueous solution. This is useful when there are so many constituents in a phase that the 2000 characters available for the constituent description list is not enough.
Constituents are not necessary on all sublattices. In the second example below, no addition is made to the first sublattice.
