Class
    Foam::exprMixedFvPatchField
 
Description
    A mixed boundary condition with expressions.
 
Usage
    \table
        Property     | Description                          | Required | Default
        valueExpr    | expression for uniformValue          | partly  | 0
        gradientExpr | expression for uniformGradient       | partly  | 0
        fractionExpr | expression for valueFraction         | partly  | depends
    \endtable
 
Note
    For fixed-value boundary conditions, can also just use
    uniformFixedValueFvPatchField with an expression for the
    PatchFunction1, or a exprMixedFvPatchField.
 
    For gradient boundary conditions, can also just use
    uniformFixedGradientFvPatchField with an expression for the
    PatchFunction1.
