CEQ is a Fortran 90 library implementing the algorithm described in "The Computation of Constrained and Unconstrained Equilibrium Compositions of Ideal Gas Mixtures using Gibbs Function Contimuation" by S.B. Pope, Cornell University Report FDA 03-02 (2003). An overview of the algorithm is also given in Gibbs function continuation for the computation of chemical equilibrium, S. B. Pope (2004), Combustion and Flame 139, 222-226.

The chemical equilibrium composition is calculated either at fixed pressure and temperature, or at fixed pressure and enthalpy. Constraints can be imposed on individual species, or on arbitrary linear combinations of species.

The CEQ software may be downloaded and used for non-commercial academic and governmewnt research. It may not be re-distributed. In publications based on the use of this implementation, we request that, in addition to the above report, you also reference this website, i.e., "CEQ: A Fortran library to compute equilibrium compositions using Gibbs function continuation", S.B. Pope (2003), http://tcg.mae.cornell.edu/CEQ.

The file README.txt contains basic instructions on downloading, installing and using CEQ. The full download is contained in the file ceq.tar (for Linux) and ceq.zip (for Windows).
