Pseudo-transient convergence criteria - PIMPLE
2 Attachment(s)
Hello.
I want to do pseudo-transient simulation using PIMPLE in pitzDaily.
When I change the default settings in fvSolution in pitzDaily, for PIMPLE to:
Code:
PIMPLE
{
nNonOrthogonalCorrectors 0;
nCorrectors 2;
nOuterCorrectors 50;
turbOnFinalIterOnly on;
residualControl
{
"(U|k|epsilon)"
{
tolerance 1e-5;
relTol 0;
}
p
{
tolerance 1e-4;
relTol 0;
}
}
}
relaxationFactors
{
fields
{
p 0.7;
pFinal 1;
}
equations
{
"U|k|epsilon" 0.8;
"(U|k|epsilon)Final" 1;
}
}
then I have residuals like in attachment. How can I know when simulation has converged to a steady state, at least according to residuals? Where can I find more information about this?
Regards,
Darko |
