Specifies the algorithm to detect zero crossings when a variable-step solver is used.
Use an improved zero-crossing algorithm which dynamically activates and deactivates zero-crossing bracketing. With this algorithm you can set a zero-crossing tolerance. See Signal threshold to learn how to set the zero-crossing tolerance.
Use the nonadaptive zero-crossing algorithm present in the Simulink® software prior to Version 7.0 (R2008a). This option detects zero-crossings accurately, but might cause longer simulation run times for systems with strong “chattering” or Zeno behavior.
The adaptive zero-crossing algorithm is especially useful in systems having strong “chattering”, or Zeno behavior. In such systems, this algorithm yields shorter simulation run times compared to the nonadaptive algorithm. See Zero-Crossing Detection for more information.
This parameter is enabled only if the solver Type is set to
