Class
    Foam::fixedNormalSlipFvPatchField
 
Group
    grpGenericBoundaryConditions grpWallBoundaryConditions
 
Description
    This boundary condition sets the patch-normal component to the field (vector
    or tensor) to the patch-normal component of a user specified field.
    The tangential component is treated as slip, i.e. copied from the internal
    field.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type            fixedNormalSlip;
        fixedValue      uniform (1 0 0);    // example entry for a vector field
 
        // Optional entries
        writeValue      false;
 
        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                      | Type    | Reqd | Deflt
      type         | Type name: fixedNormalSlip       | word    | yes  | -
      fixedValue   | User-defined value the normal component of which  <!--
                   --> the boundary is set to                          <!--
                   -->                | vectorField/tensorField | yes  | -
      writeValue   | Output patch values (eg, ParaView) | bool  | no   | false
    \endtable
 
    The inherited entries are elaborated in:

      - \link fvPatchField.H \endlink
