Dear Foamers:

During the execution of my program, I create a dictionary with the same structure than p file, which means:

{
dimensions      [0 2 -2 0 0 0 0];

internalField   uniform 101325;

boundaryField
{	
    upperwall
    {
        type            fixedFluxPressure;
        value           $internalField;
    }
	
    lowerwall
    {
        type            fixedFluxPressure;
        value           $internalField;
    }
	
    column
    {
        type            fixedFluxPressure;
        value           $internalField;
    }
	
    inlet
    {
        type            fixedFluxPressure;
        value           $internalField;
    }
	
    outlet
    {
        type            fixedValue;
        value           $internalField;
    }
	
    defaultFaces
    {
        type            empty;
    }
}
}

I need to create a volScalarField from this dictionary, but I do not know how. The only way to create a volScalarField I know is from a IOobject that reads the dictionary from a file, but I want to create it from a dictionary variable. Thanks in advance!

According to the doxygen you have either the option of IOobject or a copy construct.

Look for the "Construct from dictionary" in the header. Eg,

       //- Construct from dictionary
        GeometricField
        (
            const IOobject& io,
            const Mesh& mesh,
            const dictionary& dict
        );

Just make certain that your IOobject has the NO_READ option.
