Running Simulation - Convergence Monitoring - Head
head can be followed during the simulation. Head is plot by efficiency function object (configured in system/efficiency.fun). Simple script head.gp can plot the head during computation:
set grid
set xlabel "iterations"
set ylabel "Head [m]"
set key box above
set yrange [10.:20.]
plot "< cat ./log | grep 'head = ' | awk '{print $3}' " with lines title "Head [ m ]"
pause 10
reread
Run the script:
# gnuplot head.gp
