How to fix this error?

Error:Index exceeds the number of array elements. Index must not exceed 4.

I would like to review the simulation of this article :

A new series-connected 36-pulse rectifier with hybrid DC-reinjection method for high power output

All the Winding parameters need to have 5 elements (including both the left and right side). You have only 4.

Here is what I found out.

The parameter value needs to have 5 elements. Only 4 elements are provided, which caused the error message but it didn't tell where the error happened. So it is hard to figure it out.

If 6 elements are provided, suprisingly the error didn't happen.

So here is what it really happened (my educated guess).

There is an internal index varying from 1 to 5 to get the parameter value. When only 4 elements are provided, it will cause the "Error:Index exceeds the number of array elements. Index must not exceed 4".

The error message makes sense but it didn't really help the user. To me, it gives the impression that more elements are provided, but indeed, less elements are provided.
