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 =

DILUPBiCG: Solving for Uz, Initial residual = 0.0690214, Final residual =

GAMG: Solving for p, Initial residual = 0.011162, Final residual =

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

I guess the question is a bit outdated by now. But for the case somebody looks for it: Such settings (actually, at least most of the output settings) can be made within the /etc/controlDict file which is available in every installation to my knowledge. Setting 1 or 0 for the different Outputs should make it write the specific lines (or not)...
