about nonvirtual subsystem,how to solve it

Connections of the Physical Network cross nonvirtual boundaries. If any blocks in a Physical Network are within a nonvirtual subsystem, then all blocks of that network must be in the same nonvirtual subsystem. Either move affected blocks out of the nonvirtual subsystem, move network blocks into exactly one nonvirtual subsystem, or reconfigure affected nonvirtual subsystems to be virtual subsystems.

Hi, I encountered the same problem. Were you able to solve it?

Hi @LIU shengxiang,

The error you are observing "Connections of the Physical Network cross nonvirtual boundaries..." is a known limitation which can be found in the below MathWorks documentation link:

Instead, you can try one of the following solutions:

1. Make all related subsystems virtual (Right-click the subsystem → Subsystem Parameters → Uncheck "Treat as atomic unit")
2. Move all physically connected blocks into a single nonvirtual subsystem
3. Move all physical network blocks to the top level of the model.
