pip install scheilconda install -c conda-forge scheilTo install an editable development version with pip:
git clone https://github.com/pycalphad/scheil.git
cd scheil
pip install --editable .[dev]Upgrading scheil later requires you to run git pull in this directory.
Run the automated tests using
pytestUses classic Scheil-Gulliver theory (see G.H. Gulliver, J. Inst. Met. 9 (1913) 120–157 and Scheil, Zeitschrift Für Met. 34 (1942) 70–72.) with assumptions of
- Perfect mixing in the liquid
- Local equilibrium between solid and liquid
- No diffusion in the solid
