Problem with tutorialcase damBreak4phase under OpenFOAM15dev

jfb · February 7, 2009, 04:53

I'm using OpenFOAM-1.5-dev (svn rev. 980), compiled it (openSUSE 10.3, 64bit) and get no errormessages when running foamInstallationTest.

When running the tutorial-case multiphaseInterFoam/damBreak4phase, at the end of the first time loop, the following error message is issued:

smoothSolver: Solving for alphamercury, Initial residual = 0, Final residual = 0, No Iterations 0
mercury volume fraction, min, max = 0.0443935 0 1
air volume fraction, min, max = 0.750462 0 1
GAMG: Solving for pd, Initial residual = 1, Final residual = 0.0490662, No Iterations 1
GAMG: Solving for pd, Initial residual = 0.0154804, Final residual = 0.000357115, No Iterations 3
GAMG: Solving for pd, Initial residual = 0.000276821, Final residual = 1.03939e-05, No Iterations 5

keyword smoother is undefined in dictionary ""

file: from line 0 to line 0.

From function dictionary::lookupEntry(const word& keyword) const
in file db/dictionary/dictionary.C at line 213.

FOAM exiting

Exactly the same case seems to run fine under OpenFOAM-1.5.x (latest "git pull").

Could somebody please shed some light on this? Thanks a lot for any help!

I just tried multiphaseInterFoam/damBreak4phase with 1.5.x and it ran without any problem.

Yes, this one is my bug: I have just checked in the fix. It is to do with the format of the CD solver when GAMG is called as a preconditioner.

It runs over there, the fix is in tutorials/multiphaseInterFoam/damBreak4phase/system/fvSolution

Apologies,

Thanks very much for Your answers! Tha case runs now with both versions :-)

Hi josef
can you explane better how you fixed the fvsolution dictionary bug? I have the same error on OF 1.5-dev using an interfoam tutorial, I have the following error:

keyword smoother is undefined in dictionary ""
file: from line 0 to line 0.
From function dictionary::lookupEntry(const word& keyword) const
in file db/dictionary/dictionary.C at line 213.
FOAM exiting

Can you explane exactly how to fix it, I'm new with OF.
Thanks
Aldo

Hi,

If anyone face with this error, solution is checking the compatibility of the preconditioner with the smoother.

I solved this error by changing the preconditioner GAMG to diagonal (you may try others also such as DIC, DILU etc.)

Hope that helps someone.
