Jess is now usually supplied as the WindowsXP version on a CD-ROM as
follows.
1. The main Jess databases (including the thermodynamic
and literature reference data).
2. Executable program images only, i.e. no FORTRAN code.
The supplied codes support all the stages of calculation required
for general equilibrium modelling but not for kinetic simulations.
The database management systems and all associated programs are included,
permitting new chemical systems to be inserted and existing systems
to be modified. Subsequent stages of calculation involve (i) the generation
of sub-databases, (ii) the formulation of a suitable basis set and a
corresponding set of reactions, (iii) the determination of 'unconditional
correction coefficients' for modelling changes in temperature and ionic
strength, (iv) the establishment of appropriate mass balance equations,
(v) the solution of these equations and (vi) the output of results to
VDU, printer or spreadsheet.
Our Primer documents provide a more detailed description of JESS and
can be downloaded.
To protect our intellectual property, Jess is always supplied under
a licence agreement that prohibits copying of the system except for
installation purposes. We are also obliged to make a nominal charge
for distributing Jess to cover our various costs, including postage,
documentation and computer overheads.
