Summary0000444: rotatingWallVelocity gives error
DescriptionThe rotatingWallVelocity boundary condition gives the following error:

--> FOAM FATAL IO ERROR:
wrong token type - expected word, found on line 60 the doubleScalar 230.383

file: /nobackup/rm/felfoldi/OFsimulation/0/U::boundaryField::rotwall.*::omega at line 60.

    From function operator>>(Istream&, word&)
    in file primitives/strings/word/wordIO.C at line 74.

FOAM exiting
Steps To Reproduce"rotwall.*"
    {
    type rotatingWallVelocity;
    origin (0 0 0);
        axis (0 1 0);
        omega 230.3834;
    }

I'm also using:

"rotwall.*"
    {
    type rotatingWallVelocity;
    origin origin [0 1 0 0 0 0 0] (0 0 0);
        axis axis [0 0 0 0 0 0 0] (0 1 0);
        omega omega [0 0 -1 0 0 0 0] 230.3834;
    }

But in the latter case, i'm getting another error:


--> FOAM FATAL IO ERROR:
Expected a '(' while reading VectorSpace<Form, Cmpt, nCmpt>, found on line 58 the word 'origin'

file: /nobackup/rm/felfoldi/OFsimulation/0/U::boundaryField::rotwall.*::origin at line 58.

    From function Istream::readBegin(const char*)
    in file db/IOstreams/IOstreams/Istream.C at line 94.

FOAM exiting
Additional InformationMy case is an AMI simulation, with rotating walls.
TagsNo tags attached.

The former syntax is correct:

"rotwall.*"
{
    type rotatingWallVelocity;
    origin (0 0 0);
    axis (0 1 0);
    omega 230.3834;
}

Are you using a recent build of 2.1.x?

 No, I'm not. I checked the feature on a simplified case using the most recent build, and it works, so maybe this is the problem. I'll compile the code on our cluster and give you a feedback about my 20M cell case, if you are interested. Thank you.

The final solution is to add a "constant" keyword before the value:

"rotwall.*"
{
    type rotatingWallVelocity;
    origin (0 0 0);
    axis (0 1 0);
    omega constant 230.3834;
}

Thanks for the update

For info, in the current 2.1.x line the 'constant' entry can be omitted - these entries will fall back to the constant form for backwards compatibility
