Enables zero-crossing detection during variable-step simulation of the model. For most models, this speeds up simulation by enabling the solver to take larger time steps.
Category: Solver
Default:
Use local settings
Use local settingsSpecifies that zero-crossing detection be enabled on a block-by-block basis. For a list of applicable blocks, see Simulation Phases in Dynamic Systems
To specify zero-crossing detection for one of these blocks, open the block's parameter dialog box and select the Enable zero-crossing detection option.
Enable allEnables zero-crossing detection for all blocks in the model.
Disable allDisables zero-crossing detection for all blocks in the model.
For most models, enabling zero-crossing detection speeds up simulation by allowing the solver to take larger time steps.
If a model has extreme dynamic changes, disabling this option can speed up the simulation but can also decrease the accuracy of simulation results. SeeZero-Crossing Detection for more information.
Selecting Enable all or
Disable all overrides the local
zero-crossing detection setting for individual blocks.
This parameter is enabled only if the solver Type is set to Variable-step.
Selecting either Use local settings or
Enable all enables the following
parameters:
Time tolerance
Number of consecutive zero crossings
