Dear all,

I have a simpleFoam simulation that gives me an error I cannot explain.

Time = 20
DILUPBiCG: Solving for Ux, Initial residual = 0.0388389, Final residual = 0.0115347, No Iterations 1
DILUPBiCG: Solving for Uy, Initial residual = 0.0234663, Final residual = 0.0068901, No Iterations 1
DILUPBiCG: Solving for Uz, Initial residual = 0.0406561, Final residual = 0.0111284, No Iterations 1
DICPCG: Solving for p, Initial residual = 0.189901, Final residual = 0.0828014, No Iterations 1
DICPCG: Solving for p, Initial residual = 0.0886843, Final residual = 0.0442777, No Iterations 17
time step continuity errors : sum local = 0.0204999, global = 0.0154469, cumulative = 0.105341
DILUPBiCG: Solving for epsilon, Initial residual = 0.000536831, Final residual = 1.45236e-09, No Iterations 1
bounding epsilon, min: -0.341771 max: 2698.86 average: 62.3762
DILUPBiCG: Solving for k, Initial residual = 0.0260744, Final residual = 8.1892e-08, No Iterations 1
ExecutionTime = 117.38 s ClockTime = 118 s

Time = 21
DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 0.160163, No Iterations 1
DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 0.160163, No Iterations 1
DILUPBiCG: Solving for Uz, Initial residual = 1, Final residual = 0.160163, No Iterations 1
DICPCG: Solving for p, Initial residual = 1, Final residual = 0.401113, No Iterations 1
DICPCG: Solving for p, Initial residual = 0.274984, Final residual = 0.0935783, No Iterations 1
time step continuity errors : sum local = 5.08572e+07, global = -3.90553e+07, cumulative = -3.90553e+07
DILUPBiCG: Solving for epsilon, Initial residual = 1, Final residual = 5.23545e-06, No Iterations 1
bounding epsilon, min: -1.03964 max: 6.02868e+14 average: 2.72057e+09
DILUPBiCG: Solving for k, Initial residual = 1, Final residual = 8.27594e-06, No Iterations 1
ExecutionTime = 126.27 s ClockTime = 127 s


Can anybody help?
three iteration steps later the program crashes on FPE for the values of k and epsilon.


Thanks in advance.
