The Python version solves, for the moment, six chemical equilibrium problems (`TP, HP, SP, TV, EV and SV transformations`; where T denotes temperature, P pressure, H enthalpy, S entropy, E internal energy and V volume), always assuming ideal gases in all cases.\r\n\r\n---\r\n⚠️ **NOTE**\r\n\r\nAt the moment, the Python version does not have all the capabilities that the MATLAB version has. I will continue with the development of this version adding all the remaining capabilities. I will also add a GUI using Qt6 and Pyside6.\r\n\r\n---\r\n\r\nThe code computes the equilibrium composition by minimization of the Gibbs–Helmholtz free energy by using Lagrange multipliers, and employs NASA’s 9-coefficient polynomial fits to evaluate the thermodynamic properties. Results computed with **Combustion PyToolbox** have been validated against, and are in good agreement with, NASA’s Chemical Equilibrium with Applications (CEA) program and CANTERA.\r\n\r\nThe `MATLAB version` `also solves` `incident and reflected planar shock waves`, as well as `ideal detonations` according to Chapman-Jouguet theory and overdriven detonations, assuming always ideal gases in all cases. Along with the plain code, the new tool has been `equipped with a Graphical User Interface` developed in MATLAB 2021 under AppDesigner.\r\n\r\nThis project is also part of the PhD of [Alberto Cuadra-Lara](https://acuadralara.com/).\r\n  \r\n## Contributing\r\n\r\nPlease read [CONTRIBUTING.md](https://github.com/AlbertoCuadra/ThermochemicalCode_Python/blob/master/CONTRIBUTING.md) for details on our code of conduct, and the process for submitting pull requests to us.\r\n\r\nPlease send feedback or inquiries to [acuadra@ing.uc3m.es](mailto:acuadra@ing.uc3m.es)\r\n\r\nThank you for testing Combustion PyToolbox!\r\n\r\n## Developers\r\n\r\n* **[Alberto Cuadra-Lara](https://acuadralara.com/)** - *Main Developer*\r\n* **César Huete** - *Developer*  \r\n* **Marcos Vera** - *Developer*  \r\n\r\nGrupo de Mecánica de Fluidos, Universidad Carlos III de Madrid, Av.
