create forces
 

Hi all
I need to access the force coefficients in my solver. I am trying to move some controller device on an airfoil based on the feedback from the forces. Does any one know how it is possible to create forceCoeffs in my code ?

label id = runTime.functionObjects().findObjectID("forces");
runTime.functionObjects()[id].execute(true);


This triggers the OpenFOAM::forceCoeffs.write() which is a virtual boolean type function and writes the forces in to a file only.
The type can not be changed to return the forceCoeffs value also.

Is there any way I can make it return the values ?
