Hello,

The forces are not calculated when I include my own library in the controlDict. It seems like that nothing is run in the controlDict after I include the library. Here is my controlDict:

/*--------------------------------*- C++ -*----------------------------------*\

                outputControl outputTime;

                // Patches to sample
                patches (blade);
        // Name of fields
                pName p;
                Uname U;
        // Dump to file
                log true;
        // Density
                rhoName rhoInf;
                rhoInf 1000; //Reference density for fluid
        // Centre of rotation
                CofR (0 0 0.3);
}
);

Does someone know the way around this problem and can tell me what to do? I am using OF-1.5-dev.

Thank you.

This is rather urgent and I would be very grateful if someone had any ideas or comments.

I need the forces calculations since I want to calculate a moment on a patch.

Try this, it works for me:

forcesBlade_2
{
type forces;
functionObjectLibs ("libforces.so");
verbose true;
log true;
patches ( blade_2_NEW );
rhoName rhoInf;
rhoInf 1.225;
CofR (0 0 0);
outputControl timeStep;
outputInterval 1;
}

It calculates forces for each time step
