decomposePar error
 
Hi Foamers,

I could run waveFoam on my school HPC , however when I tried to run decomposePar

i had some error

Is there any difference to using OF231 and OF301 , in terms of using the decomposePar ?
In my system half way across the earth, i could use decomposePar in OF231, however I couldnt use it in OF301 (when i import the exact same case and files over)

Any help would be tremendously appreciated :)

Hi,

In fact the error is caused by waveAlpha boundary condition for p_rgh (and the root of the problem is design of waveTheory::New method). Currently it asks for waveProperties in object registry (waveFoam reads this dictionary and puts it into object registry, while decomposePar knows nothing about this dictionary).

So, you have several solutions

1. Remove waveAlpha BC from p_rgh.
2. Remove waveAlpha BC from p_rgh, decompose case, correct Bfs in decomposed case.
3. Correct waveTheory::New method (so it looks up dictionary in the registry first and if it fails, reads the dictionary) submit patch upstream. I.e. this piece of code

Code:
    {
        const dictionary coeffDict_
        (
            (mesh_.thisDb().lookupObject<IOdictionary>("waveProperties"))
          .subDict(subDictName + "Coeffs")
        );

        coeffDict_.lookup("waveType") >> waveTheoryTypeName;
    }
should become something like

Code:
    {
        if (mesh_.thisDb().foundObject<IOdictionary>("waveProperties")
        {
            const dictionary coeffDict
            (
                (mesh_.thisDb().lookupObject<IOdictionary>("waveProperties"))
              .subDict(subDictName + "Coeffs")
            );
            coeffDict.lookup("waveType") >> waveTheoryTypeName;
        }
        else
        {
            const IOdictionary waveDict(
                IOobject(
                    "waveProperties", mesh_.time().constant(), mesh_,
                    IOobject::MUST_READ, IOobject::NO_WRITE, false)
            );
            waveDict.subDict(subDictName + "Coeffs").lookup("waveType") >> waveTheoryTypeName;
        }       
    }
