Dear friends,
I have a very basic doubt. In simple foam, there is three continuity errors logged. In that, local is the max continuity error in a cell, global is the overall continuity error and what is cumulative? I want to plot the continuity residual in my thesis and which one should I choose (global or cumulative)? Also, one more doubt, For me there is three pressure loops with each having their own iterations and while plotting pressure residue which one should I choose, first loop or last loop? Code:
Time = 1613 smoothSolver: Solving for Urelx, Initial residual = 0.000348399, Final residual = 5.89529e-11, No Iterations 6 smoothSolver: Solving for Urely, Initial residual = 0.000141308, Final residual = 2.4223e-11, No Iterations 6 smoothSolver: Solving for Urelz, Initial residual = 0.000256047, Final residual = 3.63635e-11, No Iterations 6 GAMG: Solving for p, Initial residual = 0.00144709, Final residual = 1.13422e-06, No Iterations 10 GAMG: Solving for p, Initial residual = 0.000227054, Final residual = 2.12498e-07, No Iterations 9 GAMG: Solving for p, Initial residual = 2.1161e-05, Final residual = 1.71472e-08, No Iterations 14 time step continuity errors : sum local = 3.94777e-05, global = -1.96002e-07, cumulative = -0.018334 smoothSolver: Solving for omega, Initial residual = 3.72909e-05, Final residual = 5.341e-12, No Iterations 7 smoothSolver: Solving for k, Initial residual = 0.000210367, Final residual = 3.37588e-11, No Iterations 7 ExecutionTime = 12971.6 s ClockTime = 12999 s Time = 1614 |
