Automatic solver parameter selection

Diagnostic behavior when the software changes a solver parameter value

Model Configuration Pane: Diagnostics

Description

This parameter specifies whether the software issues no diagnostic, a warning, or an error when the software changes the value of a solver parameter during simulation. This diagnostic behavior applies when:

  • The software changes the value of a parameter with an explicitly specified value.

    For example, if you select a continuous solver for a model that does not contain continuous states, the software changes the solver selection to the discrete solver.

  • The software determines the value for a parameter with a value that specifies that the software chooses the parameter value.

    For example, when the Min step size parameter value is auto, the software determines the minimum step size.

    The software does not issue this diagnostic when determining the Solver parameter value for simulation when the value in the model is auto.

Settings

none

The software does not issue a diagnostic.

warning
