Fail to reach target error -- adjusting phase-space integration?
I am trying a process with a custom Lorentz model (by default, I ask for 10,000 events) that can be controlled with a 2-dimensional coupling. I am finding that I sometimes get a "Fall to reach target" error (only for large values of the coupling -- the process works fine for intermediate values so I don't think the issue is inherently in the model).
I have tried changing the value of the hard_survey parameter, but this doesn't seem to work:
-- when hard_survey = 0, I get 1,814 events
-- when hard_survey = 1, I get 1,096 events
-- when hard_survey = 2, I get 22 events
-- when hard_survey = 3, I get 25 events
I am wondering if there are any other parameters I can try to increase the number of events (such as second_
