Processes of the program and iRIClib subroutines

The I/O processings in solvers and grid generating programs are shown in Table 56 and Table 57 .

Table 56 I/O processings of solvers

Process
Opens a CGNS file
Initializes iRIClib
Sets up options
Reads calculation conditions
Reads grids
Reads boundary conditions
Reads geographic data (only when needed)
Outputs grids (only in cases when grid creation or re-division is performed)
Outputs time (or iteration count)
Outputs grids (only in cases when grid moves)
Outputs calculation results
Closes a CGNS file
