Shape preservation

Description

At each time step use derivative information to improve integration accuracy.

Category: Solver

Settings

Default: Disable all

Disable all

Do not perform Shape preservation on any signals.

Enable all

Perform Shape preservation on all signals.

Tips

• The default setting (Disable all) usually provides good accuracy for most models.

• Setting to Enable all will increase accuracy in those models having signals whose derivative exhibits a high rate of change, but simulation time may be increased.

Dependencies

This parameter is enabled only if you use a continuous-step solver.
