Detailed Description

Demonstration of OpenPFC ResultsWriter API for simulation output.

This example shows how to use ResultsWriter for various output scenarios:

• Binary format output (checkpointing)
• Multiple writers (full field + statistics)
• Custom writer implementation
• Parallel I/O with MPI

ResultsWriter provides a unified interface for writing simulation data to files, with built-in support for parallel MPI-IO and domain decomposition.
