Installation
============

pip (recommended)
-----------------

scheil is suggested to be installed from PyPI.

.. code-block:: bash

    pip install scheil

Anaconda
--------

.. code-block:: bash

    conda install -c conda-forge scheil

Development versions
--------------------

To install an editable development version with pip:

.. code-block:: bash

    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

.. code-block:: bash

    pytest

Theory
======

Uses 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

1. Perfect mixing in the liquid
2. Local equilibrium between solid and liquid
3. No diffusion in the solid
