Selecting a Solver
Available Solvers
SimElectronics software supports all of the continuous-time
solvers that Simscape supports:
ode23t — Trapezoidal solver
ode15s — Variable order
solver
ode14x — Fixed-step solver
You can select any of the supported solvers for running a SimElectronics simulation.
The variable-step solvers, ode23t and ode15s,
are recommended for most applications because they run faster and
copy better for systems with a range of both fast and slow dynamics.
The ode23t solver is closest to the solver that
SPICE traditionally uses.
To use Real-Time Workshop® software to generate standalone
C or C++ code from your model, you must use the ode14x solver.
For more information about code generation, see Generating Code in
the Simscape documentation.

How to Select a Solver
To specify a solver:
Open the Configuration Parameters dialog
box from the Simulation menu.
In the Solver pane (which
opens by default), select the desired solver from the Solver list.
