#include <forces/forces.H>
Calculates the forces and moments by integrating the pressure and skin-friction forces over a given list of patches.
Member function calcForcesMoment()calculates and returns the forces and moments.
Member function forces::write() calls calcForcesMoment() and writes the forces and moments into the file <timeDir>/forces.dat
