• For plotting the torque one can prepare a gnuplot script.
• The script plots the torque (moment of pressure forces) in direction of the x axis.
•  For Linux user one should prepare plotMomentOfForces.gp script

# Script for gnuplot

set title "Pressure Moment of Forces in -x direction"
set xlabel "Time [s]"
set ylabel "Moment of Forces [N.m]"


plot "< cat postProcessing/turbine-forces-and-moments/0/forces.dat | tr -d '(' | tr -d ')'" using 1:(-$11) title "Moment of Forces (-x direction)" with lines,
pause mouse

• From the case root directory run following command:

  # gnuplot plotMomentOfForces.gp

•  First process forces.dat file using following command:

  # cat postProcessing/turbine-forces-and-moments/0/forces.dat \
  | tr -d '(' | tr -d ')' > \
  postProcessing/turbine-forces-and-moments/0/forcesWithoutBrackets.dat

• This command create new file forcesWithoutBrackets.dat without brackets. Now we can open gnuplot outside cygwin and change directory to windTurbine case. Then one can start using (opening) plotMomentOfForcesWin.plt script.

# Script for gnuplot

set title "Pressure Moment of Forces in -x direction"
set xlabel "Time [s]"
set ylabel "Moment of Forces [N.m]"


plot "postProcessing/turbine-forces-and-moments/0/forcesWithoutBrackets.dat" using 1:(-$11) title "Moment of Forces (-x direction)" with lines,
