i am using simulink and getting error and unable to rectify it, please help

Error:Simulink cannot unify the dimensions of the multiplexed signal at 'Output Port 1' of 'Battery/Permanent Magnet Synchronous Machine' to match the input dimension of 'Input Port 1' of 'Battery/Simulink-PS Converter'. Specifically, Simulink cannot unify {1,1,1,1,1,1,1,1,1,1,1,1,1} to match 1. Consequently, Simulink cannot propagate dimension information from 'Output Port 1' of 'Battery/Permanent Magnet Synchronous Machine' to 'Input Port 1' of 'Battery/Simulink-PS Converter'.

Hi,

This issue appears to be a dimension mismatch between the 'Permanent Magnet Synchronous Machine' and the 'Simulink-PS Converter' blocks. In Simulink, signals can be either scalar or vector. If the connected blocks expect different signal types, it can lead to errors.

One possible cause is a configuration mismatch in the converter block. The 'Simulink-PS Converter' block might be set up to accept scalar input, while it is receiving a vector or bus signal instead.

Please verify that the output dimensions of the 'Permanent Magnet Synchronous Machine' block match the input dimensions expected by the 'Simulink-PS Converter' block. Below is a reference to a similar issue encountered.
