Are there other software packages for investigating pressure-dependent reaction networks?
Yes. The following is an (out of date, written in 2010) illustrative list of such packages:
| Name | Method(s) | Language | Author(s) |
|---|---|---|---|
| MultiWell | stochastic | Fortran | J. R. Barker et al |
| UNIMOL | CSE | Fortran | R. G. Gilbert, S. C. Smith |
| ChemRate | CSE | C++1 | V. Mokrushin, W. Tsang |
| Variflex | CSE | Fortran | S. J. Klippenstein et al |
| MESMER | CSE (+ RS) | C++ | S. H. Robertson et al |
| CHEMDIS2 | MSC | Fortran | A. Y. Chang, J. W. Bozzelli, A. M. Dean |
(MSC = modified strong collision, RS = reservoir state, CSE = chemically-significant eigenvalues)
Many of the above packages also provide additional functionality beyond the approximate solving of the master equation. For example, Variflex can be used for variational transition state theory calculations, while ChemRate provides a (Windows) graphical user interface for exploring a database of experimental data and physical quantities.
