Class
    Foam::clampedPlateFaPatchField
 
Description
    This BC provides a clamped BC. It sets zero fixed value and zeroGradient.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type                clampedPlate;
 
        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property | Description               | Type  | Reqd | Dflt
      type     | Type name: clampedPlate   | word  | yes  | -
    \endtable
 
    The inherited entries are elaborated in:
      - \link faPatchFields.H \endlink
