Hi all,
I am using libforces.so to calculate the darg and lift,
can someone please tell me what are these forces_[],

OpenFOAM-2.2.x /src /postProcessing /functionObjects /forces /forceCoeffs /forceCoeffs.C

Field<vector> totForce(force_[0] + force_[1] + force_[2]);
Field<vector> totMoment(moment_[0] + moment_[1] + moment_[2]);

List<Field<scalar> > coeffs(3);
coeffs[0].setSize(nBin_);
coeffs[1].setSize(nBin_);
coeffs[2].setSize(nBin_);

Hi,

These are the pressure force, viscosity force, and porous force, respectively.
You might want to take a look at the forces.H and forces.C:

• https://github.com/OpenFOAM/OpenFOAM...orces/forces.C

Hope this helps,
Fumiya
