hello every here,
I'm now trying to show the converge history of inlet total pressure in my case using pyFoamPlotWatcher.py.
I have got calculation log data like this:

 Time = 4

diagonal:  Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal:  Solving for rhoUx, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal:  Solving for rhoUy, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal:  Solving for rhoUz, Initial residual = 0, Final residual = 0, No Iterations 0
diagonal:  Solving for rhoE, Initial residual = 0, Final residual = 0, No Iterations 0
rho L2 Residual: 6.0569
rho LInf Residual: 7.21048

DILUPBiCG:  Solving for omega, Initial residual = 4.4485e-05, Final residual = 4.67333e-10, No Iterations 1
DILUPBiCG:  Solving for k, Initial residual = 0.015744, Final residual = 8.20384e-10, No Iterations 2

    ExecutionTime = 3.71 s

Cyclic GGI pair (per1, per2) : 3.64795 3.64795 Diff = -9.12743e-08 or 2.50207e-06 %
Mach number min = 1.00798 max = 1.42256
 Mass-Flow-Weighted Averages of p :  outlet = 122778  inlet = 84474.2
 Mass-Flow-Weighted Averages of T :  outlet = 300.108  inlet = 273.464
 MassFlows:   outlet = 14.5783  inlet = -20.3666
Expression T*_inlet :  average=288.065
Expression T*_outlet :  average=313.963
Expression p*_inlet :  average=100246
Expression p*_outlet :  average=142626

and costomRegexp file like this:

TotalPressure
{
  expr "Expression p*_inlet :  average=(%f%)";
  theTitle "TotalPressure";
  titles ( inlet );
  type regular;
}

AddToTotalPressure
{
  expr "Expression p*_outlet :  average=(%f%)";
  titles ( outlet );
  type slave;
  master TotalPressure;
}

but when I excute pyFoamPlotWatcher.py, only residuals plots are shown. And there's no error information.
Could somebody help me? Thanks!

You have to escape the special character * (asterisk) in your regular expressions.



see e.g. http://www.ispras.ru/conf/2015/pdf/Bernhard.pdf (slide 70) for a nice explanation...
