Hello FOAMers,
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: Code:
... 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(); Code:
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... /Stefan |

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? Best regards Federica |
