Hello everyone,

I've been trying to monitor the torque of the rotating blades during the running of the solver via Gnuplot.

All the residuals can be plotted with no problems. But when i introduce a line of code to monitor the torque (written every 5 iterations) gnuplot woudn't even start and gives no error out.
In the foto log_file is the placement of the value of torque i would like to monitor and in the file gnuplot is my code for it. I don't know what i'm missing or what i'm am doing wrong.

For the sake of comparison i included the line of code for mintoring the pressure residuals of the third loop by using the command " sed 'p;n;n' " which i tried to reuse to monitor the torque but doesn't seem to be the right choice.

Your help is much appreciated

Have you tried just using foamMonitor?

No i didn't use FoamMonitor.
Should it be easier to follow the simulation using FoamMonitor ?
