writing journal
 

Hello guys,
I need to output average output values on the surface named "pal". After that i need to save them in a file. I know for the average values i am going to use surface integral section in the report value. But how can i write those values into file by automatically(i.e. by inserting some sentences to the journal file)?

/solve/monitors/surface/set-monitor surf-mon-1 Integral pressure monitor-surface () no no yes output-file.txt 1 yes time-step

The above will output the integral of pressure at every timestep.

thank you very much for your answer.
Could i save the picture of the specified surface?

set the driver you want /display/set/drivers jpeg
scale the view /display/views> auto-scale
set the number of contour you want /display/set/contours> n-contour
select what contour you want to draw /display> contour
save the picture file /display/save-picture blabla.jpeg

i may have forgot a step, just play around the display sub-menu in the console...
