Class
    Foam::uniformFixedValueFvPatchField

Description
    This boundary condition provides a uniform fixed value condition.

Usage
    \table
        Property     | Description             | Required    | Default value
        uniformValue | uniform value           | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            uniformFixedValue;
        uniformValue    constant 0.2;
    }
    \endverbatim

Note
    The uniformValue entry is a Function1 type, able to describe time
    varying functions.  The example above gives the usage for supplying a
    constant value.
