DecayOS throws NaNs with Amegic's integrator — at Version 1

Description (last modified by Frank Siegert)

Using DecayOS with Amegic currently leads to a flood of warnings during integration. This only seems to be the case for proton-proton setups like below, if the initial state is changed to e+e- it works.

(run){
  OUTPUT          = 2
  EVENTS=1
  FRAGMENTATION = Off
  BEAM_1          = 2212
  BEAM_ENERGY_1   = 3500
  BEAM_2          = 2212
  BEAM_ENERGY_2   = 3500
  ME_SIGNAL_GENERATOR=Amegic
}(run)

(processes){
  Process : 93 93 ->  24[a] -24[b]
  DecayOS : 24[a] -> -11 12
  DecayOS : -24[b] -> 13 -14
  End process
}(processes)
