Daessc mode

Description

Category: Solver

Settings

Default: auto

auto

Automatically selects the optimal daessc solver mode.

Fast

The most efficient mode in terms of computation cost, but less robust.

Balanced

Provides a balance between computational costs and robustness.

Robust

More robust, but also more costly than Fast or Balanced.

Quick debug

Updates the solver Jacobian at every integration step, and is therefore even more costly than Robust. Recommended only for interactive model development, to quickly find issues with equations.

Full debug

Updates the solver Jacobian at every integration step and every Newton iteration. This mode is the most expensive in terms of computational cost. Recommended only for interactive model development, to thoroughly check equations and find possible issues.

Tips

  • The default setting (auto) usually provides a good balance between speed and robustness for most models.

  • Robust mode tends to have a higher computational cost.

  • Debug modes are the most expensive and they are recommended only for interactive model development.

Dependencies

This parameter is enabled only if the daessc (DAE solver for Simscape) solver is used.
