Why do the load flow results from the powergui block in my IEEE 34 model only appear for buses before the voltage regulator, and how can I fix this?

While working on an IEEE 34 model and using the load flow analyzer from the powergui block, I noticed that the load flow results only appear for the buses before the voltage regulator (VR). Could anyone provide guidance on how to resolve this issue? ( VR is connected between bus 814 and bus 816)

Note :when i remove the voltage regulator every bus is calculated

can you provide your model or at least an image of how the voltage regulator was implemented? It's likely you are using blocks that aren't compatible with load flow for the implementation of the regulator.

It looks like the implementation for the regulator isn't supported for load flow, aka, the tool can't do load flow through the OLTC.

What is the alternative to include in the calculation?
