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.

FOAM exiting
