FMU 블락과 함께 해석시 Solver Options -> Type은 어떤 것을 선택해야 하나요?

Variable step/ Fixed step 둘다 되나요?

FMU는 Co-simulation 특성을 가지고 있습니다.

Hi,

As per my understanding you are trying to choose a solver for the FMU block.

A solver applies different numerical methods to solve the set of differential equations that represent the model. However, no single method of solving a model applies to all systems.

The appropriate solver for simulating a model depends on these characteristics:

• System dynamics.
• Solution stability.
• Computation speed.
• Solver robustness.

You can choose the solver based on the dynamics of your model.

• A variable step solver is better suited for purely continuous models, like the dynamics of a mass spring damper system.
• A fixed step solver is recommended for a model that contains several switches, like an inverter power system.
