Hi foamers,
How can I plot application solver residuals versus iterations using pyFoam libraries?
For example for the pimpleFoam solver, that uses outer corrections to couple pressure-momentum, using following command:
pyFoamPlotRunner.py pimpleFoam
just plots residuals versus time, and so, do not show the convergence of the outer loops.
I think the solution is to plot residuals vs iterations. but how???
Thanks in advance for any reply...
Regards,
Ata.

Have a look at the customRegexp file for pyFoam. You can add your own regular expressions to scan for data in a log file, e.g. to plot the iterations the internal solver (here for Ux) needs:

solverIterations
{
	expr ".+Solving for Ux.+No Iterations (%f%)";
	theTitle "Solver Iterations";
	titles
	(
		Ux
	);
}

In your case, modify the regular expression so it captures your residuals.
