Summary0001566: Time dependant Boundary Condition crash with shallowWaterFoamSolver
DescriptionUsing time dependant BC for shallowWaterFoam solver with:
-> uniformFixedValue and table value "http://www.openfoam.org/version2.1.0/boundary-conditions.php"
or
-> groovyBC (from swak4Foam)
is impossible.

In the first case, the solver crash at first iteration.
In the second case, no crash but boundary conditions are not affected at all
Steps To ReproduceUse the attached 0/U file for the shallowWaterFoam squareBump tutorial
Additional InformationI fixed this issue using h and hU boundary conditions, instead of h and U.
In order to do that, I have modified the createFields.H of shallowWaterFoam solver like:

Info<< "Creating field hU\n" << endl;
volVectorField hU
(
    IOobject
    (
        "hU",
        runTime.timeName(),
        mesh,
        IOobject::MUST_READ,
        IOobject::AUTO_WRITE
    ),
    mesh
);

Info<< "Reading field U\n" << endl;
volVectorField U
(
    IOobject
    (
        "U",
    runTime.timeName(),
        mesh,
        IOobject::READ_IF_PRESENT,
        IOobject::AUTO_WRITE
    ),
    hU/h
);
TagsNo tags attached.

Yes, to handle complex boundary conditions it is necessary that hU rather than U is read unless special treatment to transfer BC data is implemented which is a pain. I will change the code to read hU as you suggest.
