Class
    Foam::MRFFreestreamVelocityFvPatchVectorField
 
Description
    Freestream velocity condition to be used for a wall rotating with the
    moving frame in an MRF (multi-reference frame) or SRF (single reference
    frame) case.
 
    Given the free stream velocity in the absolute frame at time 0, the
    condition applies the appropriate rotation transformation in time and space
    to determine the current freestream velocity.
 
Usage
    \table
        Property         | Description                | Required | Default value
        freestreamValue0 | freestream velocity at t=0 | yes      |
        freestreamValue  | freestream velocity at t   | yes      |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type                MRFFreestreamVelocity;
        freestreamValue0    (1 0 0);
        freestreamValue     uniform (1 0 0);
    }
    \endverbatim
