Default Automatically write Mach number field during runtime

Hey,

I am using sonicFoam on OF 2.1 and when I would like to calculate the Mach number in my domain I simply run
Code:
Mach
.

However, this is tedious and also problematic when I examine a running case via paraview, because I would have to run
Code:
Mach -latestTime
whenever a new time folder is written.

Is it possible to tell OF to calculate the Mach field at every write interval during runtime?
I have already tried to add a
Code:
systemCall
writeCalls 1( "Mach -latestTime");
to
Code:
controlDict
.
This should work for composed cases but won't work very well when running in parallel, since I would have to hardcode the root directories for each instance.

Am I missing something? Is there a better way?

Functional objects can be added to the controlDict, such as:

Code:
functions
{

    MachNumber
    {
        type                       MachNo;
        libs                        ("libfieldFunctionObjects.so");
        executeControl     timeStep;
        writeControl          writeTime;
    }

}

Hey All,
if you need the MachNumber only for last iteration, (or for old simulations) you can also create a new controldict file (such as postDict), with all the standard entry and the functionObjects and run "application -postProcessing"


Cheers,
Carlo
