PyForFluids (Python-Fortran-Fluids) is a Python package focused in the calculation of Fluid properties based on Ecuations of State (EoS). It provides a simple interface to work from Python but also exploits the high performance Fortran code for the more heavy calculations.
It’s designed with modularity in mind, in a way that new thermodyinamic models are easy to add, they even can be written either in Python or Fortran.

While nowadays there are a lot of tools for calculation of thermodynamic properties of fluids, most of them either are hard to mantain and don't have an integrated testing system or are embeded to other softwares (as spredsheat software) limiting the things that can be done to that enviroment.
PyForFluids aims to be a tool:
- With high performance, since most of it's calculations are done in Fortran
- Easy to scale due to it's modular design using the power of Python objects.
- Continuosly tested (at every
push
)to spot any problems as soon as possible.
For installing PyForFluids you just need to:
pip install pyforfluids
Make sure to check the requirements first!
Be sure to install numpy
and a fortran compiler previously, since both are
needed for the compilation of Fortran
code.
pip install numpy
- Debian-based (Debian, Ubuntu, Mint,...)
sudo apt install gfortran
- Arch-based (Arch, Manjaro, Garuda, ...)
sudo pacman -S gfortran
We recommended using the Windows Subsystem for Linux WSL
If WSL ain't being used, the native Windows wheels will be download instead, so no need to worry!
brew install gfortran
