This software models chemical reactions involving combustion, nuclear, catalyst reactor, and enzymes. It can analyze input parameters against chemical data and perform sensitivity analysis.

One of the software's strengths is its ability to quickly run Chemkin models, making it suitable for both industrial and research grade projects. Users can also utilize multiple Chemkin / freestyle thermodynamic databases.
Kintecus also boasts the capability to model isothermal / non-isothermal, adiabatic constant volume, constant pressure (variable volume) processes with ease. Users can include programmed volume, temperature, and species concentration in their models without the need for C / FORTRAN programming.
Additionally, heterogeneous chemistry can be easily modeled using Kintecus. The software can fit / optimize various parameters against users' datasets including rate constants, initial concentrations, Lindemann / Troe / SRI / LT parameters, and more. What sets Kintecus apart from other programs is its ability to fit parameters precisely at the time the data was measured with confidence bands / uncertainty analysis. The software calculates values at exactly the times specified in users' experimental datafile.
Kintecus also offers parameter scanning, bootstrapping standard errors, and metabolic control analysis via eigenvector / eigenvalue analysis. Furthermore, it can perform complex hierarchical cluster analysis on temporal concentration profiles, with or without experimentally obtained temporal concentration profiles. Users do not need to 'clean' their data, suggest interpolation methods, or specify timing meshes against their experimental data since Kintecus calculates values at exactly the times specified in the datafile.
Version 6.80: The ultra-accurate standard error calculation of fits known as bootstrapping now supports Global/local regression datasets for both global and local variable regressions with/without equation constraints with/without multiple datasets with/without uneven time steps/unlimited data points and more!
Version 5.75: Support for most of the special IUPAC chemical kinetics forms from the Master Chemical Mechanism (MCM) See iupac.pole-ether.fr Chebyshev expansions proposed for representing pressure fall off and temperature dependent rates of multiple well reactions.Reaction rates that involve families of species.
