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
orBalanced
.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.
