The main switch ``MODEL`` sets the model that Sherpa uses throughout
the simulation run. The default is :option:`SM`, the built-in Standard
Model implementation of Sherpa. For BSM simulations, Sherpa offers an
option to use the Universal FeynRules Output Format (UFO)
:cite:`Degrande2011ua`, :cite:`Darme:2023jdn`.

Please note: AMEGIC can only be used for the built-in models (SM and
HEFT). For anything else, please use Comix. For more details on the
Sherpa capabilities to simulate BSM physics see :cite:`Hoeche2014kca`.
