Residuals in the log file
 
Hi everyone,
I use cavitatingFoam, and I usually redirect the terminal output to a log file
that can be viewed later (cavitatingFoam > log).
Each time step, the code shows the following data:

***********************************
Time = 6.89243e-10

DILUPBiCG: Solving for rho, Initial residual = 0.0446275, Final residual
= 3.04602e-11, No Iterations 1
max-min rho: 869.997 865.673
max-min gamma: 0 0
DILUPBiCG: Solving for Ux, Initial residual = 0.0297357, Final residual =
4.13384e-10, No Iterations 1
DILUPBiCG: Solving for Uy, Initial residual = 0.029718, Final residual =
4.13323e-10, No Iterations 1
DILUPBiCG: Solving for Uz, Initial residual = 0.0690214, Final residual =
9.63771e-10, No Iterations 1
GAMG: Solving for p, Initial residual = 0.011162, Final residual =
3.51462e-09, No Iterations 3
max-min p: 8e+07 5.04471e+07
max(U) 20.6549
max-min rho: 869.997 855.221
max-min gamma: 0 0
GAMG: Solving for p, Initial residual = 0.00340274, Final residual =
2.19309e-09, No Iterations 3
max-min p: 8e+07 5.06173e+07
max(U) 20.6766
max-min rho: 869.997 855.306
max-min gamma: 0 0
GAMG: Solving for p, Initial residual = 0.00019062, Final residual =
2.68717e-09, No Iterations 2
max-min p: 8e+07 5.06262e+07
max(U) 20.6778
max-min rho: 869.997 855.31
max-min gamma: 0 0
ExecutionTime = 147.81 s ClockTime = 148 s

*****************************************

What can I do to avoid the lines referred to the residuals? What files do I must modify?

Thanks
