why a reusable function for Subsystem block cannot be generated?

i am working on Matlab version R2016a. i am trying to use a 3 level bridge form the library: powerlib/Power Electronics in a simulink model but when i run the simulation, an error message appears saying "Cannot generate a reusable function for Subsystem block 'modelling/<< Synthesized_Atomic_Subsystem_For_Alg_Loop_1 >>'. This subsystem is fed by the Ground block 'modelling/3-Level Bridge/Model/Ground' that has a nonscalar output signal. Either replace the Ground block with a Constant block having all zero values or modify the 'Function packaging' setting of the Subsystem block to Inline or Function This message is related to a hidden SubSystem block". The powerlib/Power Electronics is a locked library. If i try to unlock it to make the changes suggessted in the above message, then some other error message is displayed. how do i resolve this?

您解决这个问题了嘛？我也遇到类似的问题了。

I had to check the box of "break algebric loop in internal model" in the advanced tab of the "PV array" block. This is in the help document of the "PV array" bolck.

Hi Basically you can't change SIMULINK inbuilt libraries , Simulink won't allow to change libraries for security purpose. If you want any modification in three level bridge take it from Power Electronics library ,Make link disable and do the modification after that create a custom library place it. use the custom library
