Manuscript Title: HABIT: a program for predicting the morphology of molecular crystals.
Authors: G. Clydesdale, R. Docherty, K.J. Roberts
Program title: HABIT
Catalogue identifier: ABZL_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 64(1991)311
Programming language: Fortran.
Computer: VAX 11/782, VAX 6330.
Operating system: VAX/VMS.
Peripherals: disc, graph plotter.
Keywords: Crystallography, Morphology, Crystal shape, Faces, Relative growth rates And attachment energies.
Classification: 8.

Nature of problem:
The relationship between the internal arrangement of a crystal and its external appearance.

Solution method:
HABIT calculates the "attachment energy" which is the energy released on the attachment of a growth layer to the surface of a growing crystal.

The program only deals with molecular crystals and requires that parameters to describe atom-atom interactions are available (usually from the literature). However, the program comes with a number of common parameter sets installed.

Running time:
The amount of time required depends upon the nature of the material being studied.
