Detailed Description

Read field data from binary files.

This file defines the BinaryReader class for reading field data from binary files using MPI-IO. Used for:

• Loading checkpoints
• Reading initial conditions from files
• Restarting simulations

The reader handles parallel I/O with proper domain decomposition, allowing each MPI rank to read only its local portion of the data.

Usage:

pfc::BinaryReader reader;
reader.set_domain(global_size, local_size, local_offset);
reader.read("checkpoint.bin", field_data);

results_writer.hpp for writing binary files

initial_conditions/file_reader.hpp for using this in initial conditions
