CFD Online Discussion Forums - objectRegistry::lookupObject<scalar>

(I have tried to add to an existing thread of the same title initiated by Brent Craven a couple years ago but don't seem to have been successful. I'm reposting here to cover my bases. Sorry for duplication, if any).

I have followed the procedure outlined in an earlier post (quoted at bottom) to update the boundary value in the course of a run and seem to have it working. But I get a warning message that is troubling me and I'd like to eliminate it. Here is the warning:

--> FOAM Warning :
From function Field<Type>::Field(const word& keyword, const dictionary&, const label)
in file /....../Field.C at line 262
Reading "myDict" from line 0 to line 0
expected keyword 'uniform' or 'nonuniform', assuming deprecated Field format from Foam version 2.0.

Here is my coding:
The dictionary is created in createFields.H:

Code:

IOdictionary myDict

(

     IOobject

     (

        "myDict",

        runTime.constant(),

        mesh,

        IOobject::NO_READ,

        IOobject::NO_WRITE

        )

);

The variable is set in my main loop

Code:

myDict.set("myValue",aeq[m][n]);

Finally, refValue is assigned the value of this variable in updateCoeffs() (I copied inletOutletFvPatchField and customized)

Code:

const dictionary& myDict = this->db().objectRegistry::lookupObject<IOdictionary>("myDict");

this->refValue() = Field<Type>("myValue",myDict,this->refValue().size());

If I print the value of refValue over the patch it changes appropriately with changes in m and n (used in the set command). So I think it is working properly. Does anyone know how to eliminate the warning or if it can be ignored? If it can be ignored, how do I suppress printing it? I took a look at line 262 of Field.C and get lost when it appears to be using a scalar as a boolean. Any help would be appreciated. Thanks.

Yes. The methodology discussed by David above (http://www.cfd-online.com/Forums/ope...tml#post309556) worked well for me:

1. Declare the scalar as an IOobject
2. Calculate the scalar in your solver
3. Update the new scalar value with: scalarDict.set("nameOfScalar", valueOfScalar);
4. Access the new scalar value in your BC via a "db().lookupObject<IOdictionary>" (e.g., http://www.cfd-online.com/Forums/ope...tml#post309443)
