Hi guys,
a simple question... when I look at the log file of my simulation, pressure iterations never exceed 1001. How can I push this limit higher ? (Some context about my simulation: buoyantBoussinesqSimpleFoam, gmsh, 2D, air in a cavity (room), RNG k-epsilon, no gravity activated yet) Not sure what info would be useful. Just ask and I'll provide. Thank you, Fred Excerpt from the solver log file: ----------------------------------------------------------------- Time = 2 DILUPBiCG: Solving for Ux, Initial residual = 0.261689, Final residual = 0.00621137, No Iterations 1 DILUPBiCG: Solving for Uy, Initial residual = 0.254293, Final residual = 0.00587596, No Iterations 1 DILUPBiCG: Solving for T, Initial residual = 0.903778, Final residual = 0.0653779, No Iterations 1 DICPCG: Solving for p_rgh, Initial residual = 0.564181, Final residual = 0.0970861, No Iterations 1001 time step continuity errors : sum local = 0.122696, global = -0.0231034, cumulative = -0.0305711 DILUPBiCG: Solving for epsilon, Initial residual = 0.140988, Final residual = 0.00246623, No Iterations 2 DILUPBiCG: Solving for k, Initial residual = 0.327827, Final residual = 0.00701925, No Iterations 2 ExecutionTime = 39.63 s ClockTime = 39 s gradField yPlus yPlus_1 output: patch walls y+ : min = 3.57898, max = 5.48793, average = 4.04154 patch HX_ESA_baffles y+ : min = 1.23877, max = 36.751, average = 9.53288 patch Burner y+ : min = 6.46493, max = 7.91284, average = 7.11438 patch HX_ESA y+ : min = 5.66709, max = 19.7087, average = 9.87277 scalarTransport output: DILUPBiCG: Solving for AoA, Initial residual = 0.286904, Final residual = 0.00516719, No Iterations 1 ----------------------------------------------------------------- |
