generally defined boundary conditions

Hi foamers,

Following problem: I want to create a volScalarField with a given boundary condition on all the boundaries of this field. The implementation should be general and valid regardless of the number and the type of the boundaries defined elsewhere.

Here's an example. In createFields.H I want to create a field someField with boundaries

Code:

    {

        type            fixedValue;

        value           uniform 0;

    }

prescribed everywhere. Something looking like this

Code:

    volScalarField someField

    (

        IOobject

        (

            "someField",

            runTime.timeName(),

            mesh,

            IOobject::NO_READ,

            IOobject::AUTO_WRITE

        ),

        mesh,

        dimensionedScalar("someField", dimensionSet(0,1,0,0,0,0,0), 0.0),

        ???? boundaries ????

    );

The red marked piece is what I'm looking for

Hi Linch,

Replacing the red text with

Code:

"fixedValue"

should do the trick.

Good luck,

Nield
