PIMPLE ids failinfg without any warning, not sure what is the reason, when I re run the case it fails at a later time, any hints is it the GAMG solver?
PHP Code:
PIMPLE: Iteration 1
smoothSolver: Solving for U.airx, Initial residual = 2.52488e-05, Final residual = 1.39026e-10, No Iterations 1
smoothSolver: Solving for U.airy, Initial residual = 2.78076e-05, Final residual = 1.50724e-10, No Iterations 1
smoothSolver: Solving for U.airz, Initial residual = 2.89627e-05, Final residual = 1.52544e-10, No Iterations 1
GAMG: Solving for p, Initial residual = 1.13934e-05, Final residual = 7.98699e-08, No Iterations 3
GAMG: Solving for p, Initial residual = 1.81298e-06, Final residual = 1.40565e-08, No Iterations 4
GAMG: Solving for p, Initial residual = 4.10222e-07, Final residual = 3.58867e-09, No Iterations 8
time step continuity errors : sum local = 6.74827e-16, global = -1.49887e-17, cumulative = 2.22457e-14
PIMPLE: Iteration 2
smoothSolver: Solving for U.airx, Initial residual = 4.27308e-11, Final residual = 4.27308e-11, No Iterations 0
smoothSolver: Solving for U.airy, Initial residual = 3.6203e-11, Final residual = 3.6203e-11, No Iterations 0
smoothSolver: Solving for U.airz, Initial residual = 4.9941e-11, Final residual = 4.9941e-11, No Iterations 0
GAMG: Solving for p, Initial residual = 1.22209e-07, Final residual = 8.59521e-09, No Iterations 1
GAMG: Solving for p, Initial residual = 1.99213e-08, Final residual = 4.38494e-09, No Iterations 1
