hello everyone.

I obtained Cd, Cl, Cm using execFlowFunctionObjects.

------------------------------------------------------------------------------------------
forcesCoeffs
{
type forceCoeffs;
functionObjectLibs ( "libforces.so" ); // lib to load
outputControl timeStep;
outputInterval 1;
patches
(
wall // change to your patch name
);
// name of fields
pName p;
UName U;
log true; // dump to file
rhoName rhoInf;
rhoInf 1.25;
CofR ( 2.3 0.7569 0 );
liftDir ( 0 1 0 );
dragDir ( 1 0 0 );
pitchAxis ( 0 0 1 );
magUInf 1.43;
lRef 0.3537;
Aref 0.3537;

-----------------------------------------------------------------
my case is something like airfoil.

I set pitchAxis( 0 0 1 ).
in this case, which direction is positive in Cm??
clockwise? or countclockwise?

please help me
