Class
    Foam::exprValuePointPatchField
 
Description
    A fixed value point boundary condition with expressions.
 
Usage
    \table
        Property     | Description                          | Required | Default
        valueExpr    | expression for uniformValue          | yes |
        value        | initial field value                  | optional |
    \endtable
 
    The \c value entry (optional) is used for the initial values.
    Otherwise uses zero-gradient values.
