minIter for k and epsilon

johnb · May 5, 2009, 17:26

Hi,

I wonder if it is possible to specify minimum iterations “minIter” in the fvSolution for k and epsilon (well I tried and nothing happens, still results in No Iterations 0). Of course I can tighten the tolerance but shouldn’t there be away to force it to always run one iteration (i.e. minIter 1

. I am running v 1.5 and simpleFoam.

When I did look in the source code, I couldn’t find any files including minIter so maybe it isn’t implemented or used in v. 1.5?

Regards,
John

Hello there,

I have the same problem as posted above. Is there any reason, why OpenFoam does not make at least 1 iteration, even if

minIter 1;

is stated?

Best regards

Hi,

I have the same problem with minIter in OF2.1. I think this is only for the extended version...

Did you find the solution?

Thanks,
Attila

Anyone have any luck with this? I too am finding that it doesn't complete any iterations even with this option turned on.
