Example

Let us assume you want to connect your Simcenter Amesim physical model and your Simulink control model.

1. The Simulink controller has no continuous states but the Simcenter Amesim model has explicit state variables. According to table Table 11, you are in a C configuration.

2. You could verify with the Performance Analyzer that your Simcenter Amesim model is stiff (see Implicit or explicit Simulink solver (stiff or non-stiff systems)) and your Simulink model is non-stiff. Thus your configuration is C7 (see table Table 12).

3. You want to analyze your results in Simulink: you need to select either the AME2SL or the AME2SLCosim interface mode.

4. Your Simcenter Amesim model is somewhat complex and you want to benefit from the specificities and the features of the native Simcenter Amesim solver. You thus need to go for a co-simulation mode: AME2SLCosim has to be selected in this case.

5. You are not interested in performing real-time simulations and there are no specific reasons for choosing a fixed-step solver. This is why, for more performance and since it is available according to table Table 14, you will select a variable-step Simulink solver. Your configuration now is C7V or more precisely C7Vascs.

6. According to table Table 15, you should try ode45, then ode23, then ode113.

These solvers are for Simulink non-stiff systems (see Implicit or explicit Simulink solver (stiff or non-stiff systems) for details). They can be used even if the Simcenter Amesim model is stiff. Indeed, the Simcenter Amesim (variable-step) solver is still used for the Simcenter Amesim model and due to the co-simulation, it only has a limited influence on the Simulink solver, as explained in the Influence of interface modes on the Simulink solver section.
