Dear all,
I have a question about the relationship between convergence criteria and time step size. If I reduce the time step size, the residual of any variables will also decrease. Thus need I always change convergence criteria of residual with time step size? If so, is there any rule to obey for it? |

--> FOAM FATAL ERROR:
Solution convergence criteria specified in PIMPLE.residualControl must be given as single values. Corrector loop convergence criteria, if appropriate, are specified as dictionaries in PIMPLE.<loopName>ResidualControl. From function bool Foam::singleRegionConvergenceControl::readResidual Controls() in file cfdTools/general/solutionControl/convergenceControl/singleRegionConvergenceControl/singleRegionConvergenceControl.C at line 73.
