Hi
Can someone give a detailed explanation of the meaning of "initial residual", "final residual" , "Number of Iterations" and "time step continuity errors (sum local, global)"? Starting time loop Perhaps somebody can give the explanation at this example : Time = 1 BICCG: Solving for Ux, Initial residual = 1, Final residual = 0.0487822, No Iterations 1 BICCG: Solving for Uy, Initial residual = 1, Final residual = 0.0281479, No Iterations 1 ICCG: Solving for p, Initial residual = 1, Final residual = 0.00996318, No Iterations 162 time step continuity errors : sum local = 0.522641, global = -0.00525433, cumulative = -0.00525433 BICCG: Solving for epsilon, Initial residual = 1, Final residual = 1.18675e-07, No Iterations 1 BICCG: Solving for k, Initial residual = 1, Final residual = 0.0611971, No Iterations 1 ExecutionTime = 2.03 s Time = 2 BICCG: Solving for Ux, Initial residual = 0.675017, Final residual = 0.0581585, No Iterations 1 BICCG: Solving for Uy, Initial residual = 0.37357, Final residual = 0.0223893, No Iterations 1 ICCG: Solving for p, Initial residual = 0.206549, Final residual = 0.00206008, No Iterations 169 time step continuity errors : sum local = 0.64687, global = -0.00108017, cumulative = -0.0063345 BICCG: Solving for epsilon, Initial residual = 0.113535, Final residual = 9.74147e-07, No Iterations 1 BICCG: Solving for k, Initial residual = 0.443118, Final residual = 0.00468439, No Iterations 2 ExecutionTime = 2.9 s I know that the residualds give information about the convergence behavior. But i need detailed information for my seminar paper. Thanks Nico |
