Introduction > Supported interface modes
Multiple co-simulations
General remarks
If Simcenter Amesim is the target environment (mode 1.1), the co-simulation blocks are completely independent (viewed as standard submodels by Simcenter Amesim). So, the possibilities of mixing different block settings on the same Simcenter Amesim sketch are theoretically not limited.
It is possible to use several third-party models in a single Simcenter Amesim system (and vice-versa), but it is not possible to use the same third-party model several times in a single Simcenter Amesim system (and vice-versa).
There are as many co-simulation blocks used in the target environment as independent systems.
Advanced capabilities
| Capability | Supported1 Generic Co-simulation modes |
|---|---|
| Use N third-party software co-simulation blocks in Simcenter Amesim | Co-simulation: Simcenter Amesim as Master (third-party software as Slave) |
| Use N third-party software co-simulation blocks with different solver types (variable/fixed-step) or solver settings in Simcenter Amesim | Co-simulation: Simcenter Amesim as Master (third-party software as Slave) |
| Use N Simcenter Amesim co-simulation interfaces in third-party software | Co-simulation: Simcenter Amesim as Slave (third-party software as Master) |
| Use N Simcenter Amesim co-simulation interfaces with different solver types (variable/fixed-step) or solver settings in third-party software | Co-simulation: Simcenter Amesim as Slave (third-party software as Master) |
| 1. The availability of some co-simulation modes depends on the capabilities of the third-party software (master/slave relationship and possibility to co-simulate more than two tools). |
