We are working on simulink and recurdyn linkage, so could you tell me the difference between photo 1 and photo 2?

We are conducting simulink and recurdyn as co-simulation, so could you tell me the difference between picture 1 and picture 2?

In picture 1, the simulink blocks were subsystemed and then the recurdyn cosim block was outside, and in picture 2, the recurdyn cosim block was put inside without subsystem.

There's a difference in the comparison between the two. What's the difference?

If you proceed with photo number 1, it is the result of taking out the input block as it is

photo1

photo2

Hi @종원 이,

From the context given,I understand that you are trying to get know the differences between the modelling approaches used in the photo 1 and photo 2, assuming you are looking for more on subsystem use .This can be explained as follows:

In the photo 1,i.e simulink model without subsystems, the Recurdyn cosim block communicates with each individual Simulink block separately. This can result in a more detailed communication between the two software tools, but it can also make the overall model more complex and difficult to manage.

On the other hand, using subsystems in the model(as in photo2 ) can help simplify the model by grouping related Simulink blocks together into a single subsystem. This allows the Recurdyn cosim block to communicate with the subsystem as a whole, rather than with individual blocks. This can make the overall model easier to manage and can improve the efficiency of the model making.

I hope this resolves the query,Let me know if you have any further questions,

Regards,
