Class
    Foam::StationaryPhaseModel

Description
    Class which represents a stationary (and therefore probably solid) phase.
    Generates, but does not store, zero velocity and flux field and turbulent
    quantities. Throws an error when non-const access is requested to the
    motion fields or when the momentum equation is requested. Usage must
    must protect against such calls.
