The solution controls have been rewritten for use in multi-region
solvers, and PIMPLE fluid/solid solution controls have been implemented
within this framework.
PIMPLE also now has time-loop convergence control which can be used to
end the simulation once a certain initial residual is reached. This
allows a PIMPLE solver to run with equivalent convergence control to a
SIMPLE solver. Corrector loop convergence control is still available,
and can be used at the same time as the time-loop control.
The "residualControl" sub-dictionary of PIMPLE contains the residual
values required on the first solve of a time-step for the simulation to
end. This behaviour is the same as SIMPLE. The
"outerCorrectorResidualControl" sub-dictionary contains the tolerances
required for the corrector loop to exit. An example specification with
both types of control active is shown below.
PIMPLE
{
// ...
residualControl
{
p 1e-3;
U 1e-4;
"(k|epsilon|omega)" 1e-3;
}
outerCorrectorResidualControl
{
U
{
tolerance 1e-4;
relTol 0.1;
}
"(k|epsilon|omega)"
{
tolerance 1e-3;
relTol 0.1;
}
}
}
Note that existing PIMPLE "residualControl" entries will need to be
renamed "outerCorrectorResidualControl".
Application within a solver has also changed slightly. In order to have
convergence control for the time loop as a whole, the
solutionControl::loop(Time&) method (or the equivalent run method) must
be used; i.e.,
while (simple.loop(runTime))
{
Info<< "Time = " << runTime.timeName() << nl << endl;
// solve ...
}
or,
while (pimple.run(runTime))
{
// pre-time-increment operations ...
runTime ++;
Info<< "Time = " << runTime.timeName() << nl << endl;
// solve ...
}
