Summary0003455: incorrect description in forces.H
DescriptionI would like to make sure the Note on coordinate system in forces.H which reads:

\verbatim
    coordinateSystem
    {
        origin (0 0 0);
        e3 (0 0 1);
        e1 (1 0 0);
    }
\endverbatim

I tried to use local coordinate to measure wind load following wind direction.
At first, forces functionObject dictionary went like this

forces
{
  type forces;
  functionObjectLibs 1 ( ”libforces.so” );
  writeControl timeStep;
  writeInterval 1;
  patches ("hull");
  rhoName rhoInf;
  rho rhoInf;
  log true;
  rhoInf 1.21;
  coordianateSystem
  {
    origin (0 0 0);
    e3 (0 0 1);
    e1 (1 0 0);
  }
}

But the above did not work saying failed to find origin.
The next thing I found to make it work is that

forces
{
  type forces;
  functionObjectLibs 1 ( ”libforces.so” );
  writeControl timeStep;
  writeInterval 1;
  patches ("hull");
  rhoName rhoInf;
  rho rhoInf;
  log true;
  rhoInf 1.21;
  origin (0 0 0);
  coordinateRotation
  {
       type axesRotation;
       e3 (0 0 1);
       e1 (1 0 0);
  }
}

So, I am wondering if the description on the header file is incorrect.
