We present an update of the Mathematica package SARAH to calculate unitarityconstraints in BSM models. The new functions can perform an analytical andnumerical calculation of the two-particle scattering matrix of (uncoloured)scalars. We do not make use of the simplifying assumption of a very largescattering energy, but include all contributions which could become importantat small energies above the weak scale. This allows us to constrain trilinearscalar couplings. However, it can also modify (weakening or strengthening) theconstraints on quartic couplings, which we show via the example of a singletextended Standard Model.
