This PR writes custom binary files for the particles in light cone shells. VTK files (
.vtk) are written for visualization in ParaView and VisIt, and simple binary files (.bin) are written for reading in by a python script which is included in the run folderExec/ParticleFilterTest-Read_BinarySimple.py. The animation shows the particles in the light cone shells for red shifts ranging fromz=0toz=4.5for a mesh size of768x768x768 ~ 453million mesh cells. The computational domain is shown as well.Currently, this works only on CPUs. The simulation for this mesh size from
z=4.5toz=0took about 2 hrs to complete on 1024 MPI ranks (8 nodes) on Perlmutter.
