plotting the residuals
Hi everyone, I am solving flow past cylinder between two parallel channel(laminar case). I am using pisoFoam solver.After completion of iterations, i tried to plot the residuals by creating log files and then plotting by using the command ./plot. But it didn't plot anything. It also didn't create files in the log folder. Can anybody tell what might have gone wrong? Thanks in advance... regards Subhankar

Hi Subhankar,
You can use "gnuplot residuals" to plot the residuals in OpenFOAM. The following link gives a clear idea of how to use it:
