Maximum number of zero-crossings per step

Maximum number of zero crossings to locate in a single time step

Since R2022a

Model Configuration Pane: Solver

Description

When a discontinuity, or zero crossing, is detected in a simulation where you have zero-crossing detection enabled, the solver tries to determine the time at which the zero crossing occurred through an iterative process. This parameter specifies the maximum number of zero crossings the solver tries to locate within a single simulation time step.

You can adjust the bounded computational cost of the fixed-step zero-crossing algorithm using this parameter and the Maximum number of zero-crossings per step parameter.

Category: Solver

Dependencies

To enable this parameter:

Settings

2 | positive scalar integer

Allowing the solver to detect more zero crossings per step can produce a more accurate solution but is more computationally intensive.

Recommended Settings

The table summarizes recommended values for this parameter based on considerations related to code generation.
