Hello Foamers,
I am trying to use pimpleFoam and I used residualControl in the PIMPLE settings in fvSolution file: Code:
residualControl { p { tolerance 1e4; relTol 0; absTol 0; } } Code:

executing "turbulence>correct();" because pimple.turbCorr() is not 1 for some reason from pimpleFoam.C: Code:
if (pimple.turbCorr()) { turbulence>correct(); } You can take a look at the case with and without residualControl using the following two links: http://dl.dropbox.com/u/32336583/Mes...Control.tar.gz http://dl.dropbox.com/u/32336583/Mes...Control.tar.gz Thanks for your help

what does residualControl do when tolerances can be set at their own places?

I am not sure.. I am just used to it..
I am not using pimpleFoam anymore .. using pisoFoam with less timestep feels safer! Thanks for the reply..

In pimple control is by default set the flag turbOnFInallIterOnly to true. In order to get turb corr in every PIMPLE iter it is needed to specify turbOnFInallIterOnly false; in pimple control. Hope it helps, Martin
