OpenSPH Community Edition (OpenSPH-CE)

This is a fork of OpenSPH extending file format support and platform compatibility.

The original project was developed by Pavel Ševeček at the Astronomical Institute of Charles University (https://gitlab.com/sevecekp/sph).

Additions in Community Edition

Extended I/O formats

• HDF5: Native reading and writing of simulation data in HDF5 format. Supports standard OpenSPH fields as well as cosmological datasets from SWIFT, GADGET-2/4, and AREPO (/PartType0, /PartType1, and /Header attributes).
• Alembic: Export and import of point particle data to .abc format for use in external 3D software and renderers.

Solvers

• Optimization of neighbor distance calculations in AsymmetricSolver and EnergyConservingSolver.

Build system

• Windows build support using MSYS2 and UCRT64 toolchain.

Compilation

Community Edition adds optional dependencies:

• HDF5 library (enabled by -DWITH_HDF5=ON or when HDF5 is detected)
• Alembic library (enabled by -DWITH_ALEMBIC=ON or when Alembic is detected)

Compilation with CMake:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
