# SAMUS
---
Simulator of Asteroid Malformation Under Stress, package designed for Taylor et al 2022. Questions on its use should be directed to astertaylor@uchicago.edu.
This code simulates the deformation of minor bodies, assuming that they are homogenous incompressible fluid masses. They are initialized as ellipsoids and the Navier-Stokes equations are interatively solved to investigate the deformation of the body over time. This package is highly modular, and allows for user-defined output functions, size, and trajectories.
SAMUS is structured as a single large class, which allows for variables to be stored and for arbitrary function calls. A single high-fidelity simulation run can be quite lengthy, and so this allows for ease of debugging and investigation. It utilizes Python3.8 and above, and depends on the `numpy`, `FEniCS`, `DOLFIN`, `UFL`, `SciPy`, `pandas`, `quaternion`, and `mpipy` packages.
Further description of SAMUS can be found in Taylor et al 2022 (found on the ArXiv here (LINK)) and in the in-line documentation.
Examples of SAMUS's use are given in the **examples** folder.
## Installation
There are two primary methods of installing SAMUS:
1) Install through the Python Package Index (PyPI):\
`pip install SAMUS`
2) Install the developer's version on GitHub:\
`git clone https://github.com/astertaylor/SAMUS`\
`cd SAMUS`\
`python setup.py install` (Note that this command may require a `sudo` instruction.)
