Class
    Foam::exprFixedValueFvPatchField
 
Description
    A fixed value boundary condition with expressions.
 
Usage
    \table
        Property     | Description                          | Required | Default
        value        | fixed value                          | yes |
        valueExpr    | expression for uniformValue          | yes |
    \endtable
 
Note
    Can also just use uniformFixedValueFvPatchField with an expression
    for the PatchFunction1.
