Problem after Converting the simulink model from R2024a to R2022b

I have a Simulink model (1D model using simscape blocks) in R2024a. I have to generate .exe file. Bz of situation, I wanted to degrade my model to R2022b. But when I run that model in R2022b, it causing multiple errors. I have rearranged the simscape blocks there according to R2022b. Even then this error persists. What are the precautions should be taken to eliminate this error?

Hi @Vangala,

Can you share the error message and the simulink model for better understanding?

[Vangala]

Error " No of variables exceeds no of equations"

Hi guys,

Thanks for anwering the question above. I had solved it myself.

In R2022b, When you use pressure and temperature sensor, connect its A to main stream flow and B to the absolute reference. Remove unwanted sensors in the whole loop.

This method solved the issue: "No of variables greater than no. of equations".

Hi @Vangala,

This seems to be a possible bug try running the model using 'sim(bdroot)' and then clicking the hyperlinks which appear in the command window.

I hope this helps
