TrackAttenuation

TrackAttenuation is DefaultTrackDissipation:
    .doc: """
    Defines attenuation constants for high-frequency damping of each constrained degree of freedom for a Track System.
    These attenuation factors damp high-frequency oscillations above the Nyquist frequency for numerical stability.

    tensile - Attenuation factor for longitudinal tension/compression.
              Damps high-frequency oscillations during stretching and compression of track segments.

    bending_vertical - Attenuation factor for bending around the VERTICAL axis.
                       Damps oscillations in side-to-side bending of the track.

    bending_lateral - Attenuation factor for bending around the LATERAL axis.
                      Damps oscillations in sagging (bending across track width).

    shear_vertical - Attenuation factor for shear deformation along the VERTICAL axis.
                     Damps oscillations in shear deformation across the track height.

    shear_lateral - Attenuation factor for shear deformation along the LATERAL axis.
                    Damps oscillations in shear deformation across the track width.

    torsional - Attenuation factor for torsional deformation around the main track longitudinal axis.
                Damps oscillations in twisting of the track about its longitudinal axis.

Attenuation is Physics.Interactions.Dissipation.DefaultDissipation:
    .doc: """
    Attenuation dissipation model using a scalar attenuation constant.
    The attenuation value damps high-frequency oscillations above the Nyquist frequency for numerical stability.
    Typical values range from 1.0 to 2.0, with higher values providing stronger high-frequency damping.
