Class
    Foam::uniformFixedValueFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    This boundary condition provides a uniform fixed value condition.
 
Usage
    \table
        Property     | Description                  | Required | Default
        uniformValue | uniform value                | yes |
        value        | initial field value          | optional |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            uniformFixedValue;
        uniformValue    constant 0.2;
    }
    \endverbatim
 
Note
    The uniformValue entry is a PatchFunction1 type,
    able to describe time and spatial varying functions.
    The example above gives the usage for supplying a constant value.
 
    The \c value entry (optional) is used for the initial values.
    Otherwise the \c uniformValue is evaluated.
    In some cases (eg, coded or expression entries with references to other
    fields) this can be problematic and the \c value entry will be needed.
