Outputting time (or iteration count)

Outputs the timestamp information or the iteration count to the CGNS file.

Be sure to perform this before outputting the calculation grid or calculation results.

Also note that the time and iteration-count information cannot be output at the same time. Output either, not both.

Subroutine

Remarks

cg_iric_write_sol_time_f

Outputs time

cg_iric_write_sol_iteration_f

Outputs iteration count

List 100 shows an example of source code to output timestamp information.
