It's the one with the near-zero chemical affinity . Before executing the model calculation, fractionation mode must be invoked. The default mode of crystallization is equilibrium mode . Go to the options menu and select the Fractionation entry. At this stage the initial conditions and reaction path constraints have been specified.
Modeling results are output to the display and to a number of disk files .
The user may change bulk composition or model constraints and restart the calculation using the same menu entry. A manual page describes many common numerical problems that may occur when the program is running. Exit the program by invoking the Exit entry of the Commands menu.
