pyMARS
Automatically reduces large chemical kinetic models into smaller ones that stay accurate over the conditions you care about, using established skeletal reduction methods.

Kyle E. Niemeyer, Ph.D.
We are recruiting a Ph.D. student to work on a funded position, open until filled. Please see the description on the Lab page.
We build open-source software for science and engineering.
Much of our research produces software, and we release it openly so others can use, check, and build on it. Some of these packages we lead ourselves; others are community projects we help develop and maintain. Most are described in more detail in our publications.
Packages 🔗︎
MC/DC
Monte Carlo / Dynamic Code: a community Python package for fully transient neutron transport that performs efficiently on high-performance-computing systems through just-in-time compilation, while staying quick to prototype new methods. Our group contributes to its development.
💻︎ mcdc-project/mcdc 📖︎ Documentation
PyKED
Python interface to the ChemKED format, for validating and working with data files describing fundamental combustion experiments.
💻︎ pr-omethe-us/PyKED 📖︎ Documentation
PyTeCK
Automatically evaluates chemical kinetic models against experimental data, so a model's performance can be measured reproducibly rather than by hand.
💻︎ pr-omethe-us/PyTeCK 📖︎ Documentation
Cantera
A widely used open-source toolkit for problems involving chemical kinetics, thermodynamics, and transport. The group has contributes to its development and maintenance.
💻︎ Cantera/cantera 📖︎ Documentation
pyJac
Generates analytical Jacobian matrices in C and CUDA for chemical kinetics ODE systems, which integrate faster and more accurately than the finite-difference approximations they replace.
💻︎ SLACKHA/pyJac 📖︎ Documentation
Data and teaching materials 🔗︎
Not software packages, but openly released and maintained the same way.
ChemKED database
A collection of ChemKED files capturing fundamental combustion experiments, like autoignition and flame speed measurements, in a human- and machine-readable form.
