SimpleX
SimpleX
SimpleX is a computer software package for radiative transport of ionizing radiation in complex geometries. The method is fast and features an unstructured computational mesh with adaptive resolution. Features of the current release of SimpleX include:
- Use of a naturally adaptive Voronoi-Delaunay mesh. This allows for computations on both regular gridded hydrodynamic data and SPH data.
- Computational cost independent of number of sources.
- Heating and cooling of the medium (hydrogen only for the moment).
- MPI parallel implementation in C++ package.
- Possibility to do radiation-hydrodynamics within the AMUSE framework.
The SimpleX distribution
SimpleX2.0 can be downloaded as a tar-gz file here. The file is big (86 Mb) because the HEALPix and QHull packages are included in full. The manual can be downloaded here separately (but is also included in the package).
In development
Several features are not included in this release but are being tested at the moment. Most of these will be included in future versions. A non-exhaustive list contains
- Helium physics.
- Diffuse recombination radiation.
- Restart files (for crashed or long simulations).
- More memory efficient implementation.
- More modular/cleaner code.
