• For interFoam solvers is useful to watch fraction of phases volumes

   

• Liquid phase volume fraction is part of solver output

   

• Write small gnuplot script showing Liquid phase volume fraction during computation

   

• Create file named volumePhaseFraction:
  

   

# Gnuplot script file for plotting data from file "log"
set title "Convergence process"
set xlabel "Iterations"
set ylabel "Liquid phase volume fraction"
set grid
plot '< cat log | grep "Phase-1" | cut -d " " -f5 ' with lines title 'Liquid phase volume fraction'
pause mouse
reread

• Run gnuplot with volumePhaseFraction file on log-file named log:
  

  # gnuplot volumePhaseFraction
