Co-simulation interface

Co-simulation interface

There are two ways to create an interface with Simulink: the standard interface and the co-simulation interface. Here we will explain what the differences are between the two, and describe how to use the co-simulation interface.

The main difference between the two interfaces is that the co-simulation interface uses two (or more) solvers, while the standard interface uses only one. This means that Simcenter Amesim and Simulink use their own solvers for the co-simulation interface whereas they both use the Simulink solver for the standard interface. Another difference is that with the standard interface the Simcenter Amesim part is seen as a time continuous block in Simulink and in the co-simulation it is a time discrete block. Since the co-simulation block is seen as a discrete block it makes this interface very suitable for discrete controllers implemented in Simulink controlling a Simcenter Amesim model.
