|Fixed in Version||dev|
|Summary||0003513: pimpleFoam - residualControl does not have any effect when using the functionOnject scalarTransport|
|Description||In report 0003510, the issue with steady solvers was fixed. Now it works great.|
Now I am doing the same test with unsteady solvers and I found that the issue is still there.
Personally speaking, for unsteady solvers this is not a big deal (my opinion). However, I think it is a good idea to have a consistent behavior among the solvers.
If you set outerCorrectorResidualControl to a large value, i.e.,
relTol 1; //0.01 - 0.001
tolerance 1; //0.001 - 0.0001
I would expect the loop to stop almost immediately, but it does not.
I also found that if you use residualControl, the solver will read this condition as well.
I think the use of residualControl is redundant. The condition outerCorrectorResidualControl should be enough to control the loop. In my personal opinion, residualControl makes sense only to assess if the solver has reached a steady behavior (maybe this is the desired behavior, I don't know).
Maybe a way to solve this issue, will be to add the tolerance in the function object scalarTransport, but this fix will be only valid for this specific function object.
Again, I think this is more an annoying behavior than a bug.
|Steps To Reproduce||In the attached case run the script run_all.sh:|
$> sh run_all.sh
The tolerance of the transported scalar is high, so I would expect the solver to stop immediacy, but it does not.
