Reading forces from previous time step within solver

what would be the best way of reading forces from previous time step within solver code? I'm calculating some cases with OF 1.6 via simpleFoam.
I noticed the function objects where pressure and viscous forces/moments are integrated over given walls (using "libforces.so"). In forces.C the
data of interest accessed by:
... fm.first().first() (pressure forces) or fm.first().second() (viscous forces) fm.second().first() (moment of pressure forces) or fm.second().second() (moment of viscous forces) ... return fm; ... fm.write();
scalar Fp = fm.first().first(); scalar Fv = fm.first().second();
I'm not familiar with the code conventions of OF and new to object oriented programming in C++! Any advice is much appreciated...

I know that this is an old post but I'm very interested in it. Have you found a solution to that problem? I need to customize a restraint library inserting pressure and viscous forces calculated in the previous time step.
Do you have any suggestion?
