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.

Table 74 Subroutines to use

Subroutine

Remarks

cg_iric_write_sol_start

Starts outputting calculation results

cg_iric_write_sol_end

Ends outputting calculation results

cg_iric_write_sol_time

Outputs time

cg_iric_write_sol_iteration

Outputs iteration count

List 167 shows an example of source code to output timestamp information.
