I am working on calculation of water resistance on the hull of a ship. But I could not find a way to output the drag force values. I have been using a function in contolDict which reads as below:


libs
(
"libOpenFOAM.so"
"libforces.so"
);
functions
{
forces
{
type forces;
functionObjectLibs ("libforces.so");
outputControl timestep;
outputInterval 10;
patches (hull_patch0);
pName p;
UName U;
rhoName rhoInf;
log true;
rhoInf 1025*alpha1*100;
cofR (0.25 0.007 0.125);
}


Does this function output the force upto the water level of the hull or the complete hull?
