Class
    Foam::rotatingWallVelocityFvPatchVectorField
 
Group
    grpWallBoundaryConditions grpGenericBoundaryConditions
 
Description
    This boundary condition provides a rotational velocity condition.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        origin       | origin of rotation in Cartesian coordinates | yes|
        axis         | axis of rotation        | yes         |
        omega        | angular velocty of the frame [rad/s] | yes    |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            rotatingWallVelocity;
        origin          (0 0 0);
        axis            (0 0 1);
        omega           100;
    }
    \endverbatim
 
    The \c omega entry is a Function1 of time, see Foam::Function1Types.
