Detailed Description

Read initial conditions from binary file.

This file defines the FileReader class, which reads field values from a binary file to initialize simulation state. Useful for:

• Restarting simulations from checkpoints
• Loading pre-computed initial conditions
• Continuing interrupted simulations

The binary file format must match the expected field layout (domain size, decomposition, data type).

Usage:

auto ic = std::make_unique<pfc::FileReader>("checkpoint.bin");
ic->set_field_name("density");
simulator.add_initial_condition(std::move(ic));
