Continuous state refinement method

Method daessc solver uses to refine continuous state values

Since R2025a

Model Configuration Pane: Solver

Description

The Continuous state refinement method parameter specifies the method the daessc solver uses to refine continuous state values between major time steps.

Dependencies

To enable this parameter:

  • Set the solver Type to Variable-step.

  • Set the Solver parameter to daessc (DAE solver for Simscape).

Settings

Solver interpolation (default) | Solver stepping
Solver interpolation

Use solver interpolation between major steps for zero-crossings detection and state refinement. This option is more efficient and works well for most models.

Solver stepping

Use solver discretization method, effectively taking shorter steps between the major steps and applying the solver discretization formula at refined points. This option has higher computational cost but for some models it may produce a solution that better satisfies the equations and avoids spikes at zero crossings.

Programmatic Use
