FastChem 4.0

This is the new version 4.0 of FastChem. It removes the requirement of quad-precision calculations at low temperatures and can run on platforms that only support double precision without restrictions. This release also adds new elements with their associated gas-phase species and condensates.

FastChem 3.1.3

Some improvements related to convergence speed and new API functions added.,

FastChem 3.1.2

Add automatic PyPI binary wheels and separate documents branch.

FastChem 3.1.1

The behaviour of condensation calculations with phase violation has been changed. Now, before stopping the calculation and returning a phase rule violation flag, FastChem will re-calculate the gas phase and provide the corresponding number densities of species still left in the gas phase. However, note that those species will not sum up to the correct input pressure!

FastChem 3.1

The new version 3.1 of FastChem Cond (FastChem 3.x) includes changes in the calculation of the gas-phase chemistry.

FastChem Cond

This new version, called FastChem Cond, adds equilibrium condensation and the rainout approximation to FastChem. Additionally, data for almost 300 solid and liquid condensate species has been added.

FastChem 2.1.1

Some small bugfixes

FastChem 2.1

FastChem now supports installation via Python by either using the setup.py script from the root directory or installing the pyfastchem package from PyPI.
