Cantera 2.2.0

New major version. Highlights include:

• Reformulated multicomponent diffusion calculation to improve 1D solver convergence.
• Introduction of Species and Reaction classes which can be used to construct and modify ThermoPhase / Kinetics objects on-the-fly, without necessarily using CTI/XML input files. See the new examples extract_submechanism.py and mechanism_reduction.py.
• Better handling of CTI and XML files: Parsed CTI and XML files are cached based on modification time and file content, and implicit conversions are done without generating .xml files. Phases can be imported directly from XML or CTI strings. Both CTI and XML files can import species and reactions from other CTI or XML files.
• Enable re-initialization of reactor networks, which improves efficiency for integration with CFD-like codes - see the example surf_pfr.py.
• Introduction of a simple radiation model for flames (optically thin, gray gas for CO2 and H2O) - see the example diffusion_flame.py.
• Efficient sensitivity analysis of 1D flame solutions (see flamespeed_sensitivity.py).
• Added strain rate calculations for diffusion flames (see diffusion_flame_extinction.py and diffusion_flame_batch.py).
• Added premixed counterflow flame configuration to Python module (see premixed_counterflow_flame.py).
• Allow Sundials to link to external (optimized) BLAS/LAPACK libraries.
• Support for Sundials 2.6.
• Updated Matlab toolbox documentation, which is included in the online HTML documentation.

Cantera 2.1.0

Some of the major improvements since the release of Cantera 2.0 are:

• A new Cython-based Python interface, with a streamlined API and support for Python 3.2 and higher (as well as Python 2.6 and 2.7)
• Reformulation of reactor governing equations to improve performance and robustness, especially for larger mechanisms, including the addition of reactor types specifically optimized for ideal gases
• Improved support for reactor network sensitivity analysis
• Support for "chemically activated" reaction rate parameterizations
• Better support for importing "Chemkin"-format mechanisms using ck2cti.py
• Numerous improvements to performance and robustness of the 1D solver
• More comprehensive save/restore feature for 1D simulations
• Test suite coverage of the 1D flame module
• Support for compilation using Visual Studio 2012
• Extensive clean-up of Doxygen documentation

Cantera 2.0.2

• Maintenance release fixing issues identified in Cantera 2.0.1.

Cantera 2.0.1

• Maintenance release fixing issues identified in Cantera 2.0.0.

Cantera 2.0.0

This release of Cantera focuses on improving compatibility with all supported operating systems (Linux/Unix, Windows, and OS X) by introducing a new SCons-based build system. This version adds support for newer versions of several related projects: Python 2.7, NumPy, MinGW, and Sundials 2.5. Many bugs which affected previous versions of Cantera have been fixed.
