All low-level parallel bits:

• support for surfaceFields
• low-level distributed Field mapping
• complete rewrite of redistributePar

Just stumbled over this. Unfortunately with UniformDimensioned the name gets taken from the dimensioned type instead of the object.

Might need to have this instead:

new uniformDimensionedScalarField
(
    io,
    dimensionedScalar(rio.name(), dimLength, masterLen)
)

With GeometricField only the dimensions and value of the dimensioned type are relevant (which is a good thing).

Agree:

dimensionedScalar(rio.name(), dimLength, masterLen)

Another option would be to make it all consistent with other DimensionedFields by favouring the regIOObject name. Eg, in UniformDimensionedField itself

virtual const word& name() const
{
    return regIOObject::name();
}

virtual void rename(const word& newName)
{
    regIOObject::rename();
    dimensioned<Type>::name() = regIOObject::name();
}

And in the constructor:

template<class Type>
Foam::UniformDimensionedField<Type>::UniformDimensionedField
(
    const IOobject& io,
    const dimensioned<Type>& dt
)
:
    regIOobject(io),
    dimensioned<Type>(io.name(), dt.dimensions(), dt.value())
{
    // Read value
    readHeaderOk(IOstream::BINARY, typeName);
}


template<class Type>
Foam::UniformDimensionedField<Type>::UniformDimensionedField
(
    const UniformDimensionedField<Type>& rdt
)
:
    regIOobject(rdt),
    dimensioned<Type>(rdt)
{
    dimensioned<Type>::name() = rdt.name();  // safety
}

No, quite happy with it being a wrapper around a dimensioned type.
