FLUENT 6 - writing residual plots when running in batch mode
|
When running FLUENT in batch mode one may wish to monitor the solution progress by viewing the residual history and monitor plots. Monitoring the progress of a FLUENT simulation run in batch mode can be easily done by periodically writing image files containing residuals and monitors. The following section from a FLUENT journal file demonstrates how this can be accomplished. Note that writing image files while running in batch mode requires a null driver to be specified for the graphics. This is done using the -gu -driver null options when starting FLUENT. For example, fluent 3d -gu -driver null -i batch_journal_file.jou & Journal commands: ; set up hardcopy attributes (modify as desired) display set hard-copy color-mode color display set hardcopy driver jpeg display set hardcopy landscape? no display set hardcopy invert-background? yes ; ; set up residual plotting solve monitors residual plot? yes solve monitors residual window 0 ; ; iterate solve iterate 1000 ; ; write image file of residuals display set-window 0 display hard-copy Residuals.jpg ; Options: 1. Usually it is desirable to write residual plots periodically. ; iterate solve iterate 500 ; ; write image file of residuals display set-window 0 display hard-copy Residuals_1.jpg ; ; iterate solve iterate 500 ; ; write image file of residuals display set-window 0 display hard-copy Residuals_2.jpg ; ; iterate solve iterate 500 ; ; write image file of residuals display set-window 0 display hard-copy Residuals_3.jpg ; 2. Images of convergence monitors can also be created. For example, ; create a point to monitor the velocity surface point-surface point-1 -0.02 0.15 0.1 ; ; set up a convergence monitor solve monitors surface set-monitor point-monitor-1 phase-1 velocity-magnitude point-1 () yes 1 yes yes point-1-vel-mag.dat yes "Vertex Average" ; ; write image file display set-window 1 display hard-copy Monitor_1.jpg |
