pyGraSPH

A Python, and super basic, version of GraSPH. Early stages of development. Only in 2D.

Setup

Package requirements:

pip install git+https://github.com/edoyango/pyGraSPH.git

NumPy version 1.25 is used here as performance improvements are introduced which improve speed of this code by 4x. See NumPy Release Notes, where the improvements to np.ufunc.at and np.einsum are most relevant.

Run

Edit main.py as needed, then

mkdir output # make output directory if doesn't exist
python3 main.py

and wait awhile.

Plotting

Edit plot.py as needed, then

python3 plot.py <timestep>

which reads data form output/sph_*.h5 and creates sphplot.png in the current working directory
