Hi,

I'm trying to make a custom regular expression for my force coefficients so I can plot them on the fly with pyFoamPlotWatcher.py, but I'm not really sure on how my customRegexp file should look like. Does anybody have an working example?

My force coefficient output looks like this btw:

forceCoeffs forceCoeffs output:
    Coefficients
        Cm       : -2.34093e-05    (pressure: -2.32145e-05    viscous: -1.94815e-07)
        Cd       : -0.010548    (pressure: -0.0105261    viscous: -2.18705e-05)
        Cl       : -0.010548    (pressure: -0.0105261    viscous: -2.18705e-05)
        Cl(f)    : -0.00529742
        Cl(r)    : -0.0052506

Thanks!

Anyone? Or can someone point me in a direction where I could find more resources for customregexp for pyfoam?

You can create one regexp for each line of your force coefficient output, and then use the new master-slave feature to merge all data into a single plot.

This is how your file customRegexp could look like:

dragOF5 {
	theTitle "Forces";
	expr "Cd += (%f%)";
	titles ("Drag Coeff");
}
dragOF5slave
{
	expr "Cl += (%f%)";
	titles ( "Lift Coeff" );
	type slave;
	master dragOF5;
}

The regular expression is told that there might be an arbitrary number of spaces between the keyword "Cd" and the equal sign using the plus sign.
