Introduction

Griddr is a utility to efficiently smooth SPH (Smoothed Particle Hydrodynamics) particle data onto regular 2 and 3D grids.

If you wanted to make an image of a cube centred on the origin with side length 10 you would simply have to write:

./Griddr-P --p ParameterFile --gdx 10 --gdy 10 --gdz 10

For an in-depth guide to installing Griddr, see Installation.

Features

  • Reads Gadget2 binary and HDF5 file formats
  • Smooths any data discovered in a HDF5 file
  • Accurately calculates SPH field values at the position of each pixel
  • Multiple smoothing kernels available
  • Outputs data as .csv files (more formats on the way)
  • Python wrapper available
  • Optionally accounts for perspective and dome/fisheye projections
  • Some use of OpenMP acceleration
