Hi,

I need to create a tensorfield for the creation of the hydrodynamical dispersion tensor after Scheidegger.The entries depend on the two constants alphaL and alphaT as well as on different velocity components.


When I define the tensor with constant entries everything worked fine:

dimensionedScalar alphaL
(
transportProperties.lookup("alphaL")
);

dimensionedScalar alphaT
(
transportProperties.lookup("alphaT")
);


volTensorField Dhyd
(
IOobject
(
"Dhyd",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh,
dimensionedTensor("Dhyd", dimensionSet(0,2, -1, 0, 0, 0, 0),tensor(0,0,0,0,0,0,0,0,0))
);

But it did not compile if I make these entries depending on alphaL or on velocity components like:

tensor(alphaL,0,0,0,0,0,0,0,0)

or

tensor(velocity.component(0),0,0,0,0,0,0,0,0)

I get the message, that only one argument is expected for the tensor, but 9 are given.
Does anybody know, how I can define these entries for the tensor depending on the velocity components and on the alpha-values?


Thanks for your help
