Plot continuity error in transient simulation
 
Hi Foamers,
Would you please tell me how can I plot continuty residuals at the end of simulation and also, local residual along simulation.

Is there someone to guide me how can I plot continuty error?!
Shall I implement the below code in my controlDict/function?
thanks.
Code:
continuityError1
{
    // Mandatory entries (unmodifiable)
    type            continuityError;
    libs            (fieldFunctionObjects);

    // Optional entries (runtime modifiable)
    phi            phi;

    // Optional (inherited) entries
    writePrecision  8;
    writeToFile    true;
    useUserTime    true;
    region          region0;
    enabled        true;
    log            true;
    timeStart      0;
    timeEnd        1000;
    executeControl  timeStep;
    executeInterval 1;
    writeControl    timeStep;
    writeInterval  1;
}

}
This works too.
