sphinterp 0.0.1

Smoothed particle hydrodynamics interpolation to a grid.

sph-interp

Smoothed particle hydrodynamics interpolation to a grid.

The core functionality of sph-interp is a set of interpolation functions derived from the Splash Fortran code rewritten in Python. It uses numba, a Python JIT compiler, for performance on par with the Fortran code.

For the original Splash source code, see https://github.com/danieljprice/splash.

Usage

Import sph-interp.

>>> import sphinterp as interp

Interpolate particles via projection.

>>> pixel_grid = interp.projection(x, y, z, h, weight, data, ...)

Install

Install from source.

git clone https://github.com/dmentipl/sph-interp
cd sph-interp
pip install -e .

Requirements

Python 3.6+ with numpy and numba.
