Overview of Simultaneous Events

During a simulation, multiple events can occur at the same value of the simulation clock, whether or not due to causality. Also, the application treats events as simultaneous if their event times are sufficiently close, even if the event times are not identical. Events scheduled on the event calendar for times T and T+Δt are considered simultaneous if 0 ≤ Δt ≤ 128*eps*T, where eps is the floating-point relative accuracy in MATLAB software and T is the simulation time.

This table indicates sources of relevant information that can help you understand and manage simultaneous events.
