## Overview

CMFSN is presented as a computational fluid-and-structure simulation project for transonic aircraft, with a stated goal of modeling three-dimensional viscous subsonic and transonic flow and structural deformation. The tree suggests CAD exchange, mesh exchange, fluid and structural solvers, a solver handler, and a UI as distinct product areas. However, the sampled implementation is skeletal: main.cpp only prints a greeting, and the sampled CAD/mesh source files are empty. The available evidence does not establish a runtime user-to-result workflow or connections among these subsystems.
