Hello,

when running scalartransportfoam I have a recurring pattern:
The number of iterations is usually low, but sometimes has a peak of 1001:

Code:
DILUPBiCG:  Solving for T, Initial residual = 4.84629e-05, Final residual = 2.53325e-14, No Iterations 6
Time = 1.23818

DILUPBiCG:  Solving for T, Initial residual = 4.84519e-05, Final residual = 334.649, No Iterations 1001
Time = 1.23838

DILUPBiCG:  Solving for T, Initial residual = 0.0346593, Final residual = 6.09668e-13, No Iterations 8
Time = 1.23858
Does this do any harm to my solution? It does, I suspect..

Thanks in advance
