Tangent runs log the energy parts of run and tangent per block (kinetic, bending, linear membrane; the run's true membrane energy), since the linear membrane energy is inflated at large deflection; tangent cache keys carry TANGENT_VERSION = 2

Tangent runs (numerics.tangent): integrate the derivative of the run with respect to a relative change of the prescribed peak forces by forward-mode differentiation of the step; its sound, probes, frames and an energy norm per block are stored in the .cymsim file (group tangent), and tangent runs continue and are cut like plain runs
