Class
    Foam::functionObjects::icoUncoupledKinematicCloud

Group
    grpLagrangianFunctionObjects

Description
    This functionObject tracks a uncoupled kinematic particle cloud in the
    specified velocity field of an incompressible flow (laminar, RANS or LES).

    It may be used in conjunction with any transient single-phase incompressible
    flow solver such as pisoFoam or pimpleFoam and tracks the particles or
    parcels without affecting the the flow-field.

    The kinematicCloud requires the the density of the fluid which is looked-up
    from constant/transportProperties dictionary and the acceleration due to
    gravity which is read from the constant/g file if present or defaults to
    zero.

    The kinematicCloud properties are read from the
    constant/kinematicCloudProperties dictionary in the usual manner.

    Example of function object specification:
    \verbatim
        tracks
        {
            libs        ("liblagrangianFunctionObjects.so");
            type        icoUncoupledKinematicCloud;
        }
    \endverbatim

Usage
    \table
        Property | Description                     | Required   | Default value
        type     | Type name: icoUncoupledKinematicCloud | yes  |
        U        | Name of the velocity field       | no        | U
        kinematicCloud | Name of the kinematicCloud | no        | kinematicCloud
