mod_mesh_io Module

Input/Output routines for native hexahedral mesh files.

This module handles the parsing of the ASCII-based native mesh format used by the solver. It reads node coordinates, cell connectivity, face metrics, and boundary patches from the directory specified in the case parameters.


Uses


Subroutines
