Hello,



I'm new here and I've looked through several forums and google searches with no luck on this issue, but feel free to redirect me if I have overlooked something. I am trying to read in a custom volScalarField, "R", using blockMesh. Should be pretty straight forward but I have a few blocks and I want a different value of "R" in one of the blocks. See the code snippets below.


blockMeshDict:


Code:
.
.
blocks
(
    hex ( . . . ) Region_0 ( . . . ) simpleGrading ( . . . )
    hex ( . . . ) Region_1 ( . . . ) simpleGrading ( . . . )
    .
    .
    .

    hex ( . . . ) Region_5 ( . . . ) simpleGrading ( . . . ) 
);
.
.
R:


Code:
.
.
FoamFile
{
    version     2.0;
    format      ascii;
    class       volScalarField;
    object      R;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions      [0 1 -2 0 0 0 0];

internalField
{
    Region_0
    {
        type            fixedValue;
        value           0;
    }

    Region_1
    {
        type            fixedValue;
        value           0;
    }
.
.
.
    Region_5
    {
        type            fixedValue;
        value           10E10;
    }
}
.
.
.
createFields.H:


Code:
.
.
Info <<"Reading field R\n" <<endl;
volScalarField R
(
    IOobject
    (
       IOobject::groupName("R",continuousPhaseName),
       runTime.timeName(),
       mesh,
       IOobject::MUST_READ,
       IOobject::AUTO_WRITE
    ),
    mesh
);
.
.
When I run blockMesh I get no error, but when I try to run my solver I get the following message:


Code:

Reading field R



--> FOAM FATAL IO ERROR: 
Attempt to return dictionary entry as a primitive

file: . . . /0/R.internalField from line 23 to line 54.

    From function virtual Foam::ITstream& Foam::dictionaryEntry::stream() const
    in file db/dictionary/dictionaryEntry/dictionaryEntry.C at line 83.

FOAM aborting

Any help is appreciated!

If you're only trying to set the values of R in one of your regions, why not try the setFields utility? The utility allows you to set the values of a field within a subsection of cells -- selected with boxToCell, for example. Here is a link to an example from one of the tutorials : https://github.com/OpenFOAM/OpenFOAM.../setFieldsDict.

Hi Caelan,


That seems to do the trick for this case! Thanks for the help
