Cannot get simulation to run after 2024 upgrade from 2023.

I upgraded from MATLAB/SIMULINK 2023 to 2024. When trying to rerun the simulation that had run in 2023 I get:

"

Error:Unable to update models referenced by 'plant'.

Caused by:

The corresponding 'decay_heat_SF.tlc' file for the MATLAB S-function 'decay_heat_SF' in block 'decay_heat/Level-2 MATLAB S-Function' must be located in the current working directory, the MATLAB S-function directory 'D:\OneDrive\USNC\Control Design\Decay Heat', or the directory 'D:\OneDrive\USNC\Control Design\Decay Heat\tlc_c'

"

Under 2023b no "decay_heat_SF.tlc" was generated or needed.

When running "decay_heat_SF" as a standalone model it runs. When added as a sub-model in "plant" it gives this error.

Can someone help?

I am answering my own question.

It seems that when running a "referenced" model in SIMULINK version 2024 it defaults to a "Accelerator" in the "Simulation mode" instead of "normal" which I suspect was the default in 2023. As I an relatively new to SIMULINK and the fact that it compiles in the "accelerator" mode I was getting an error I did not really understand.

Once I switched to "normal" the SIMULATION ran as per normal. Presently, whilst debugging the model, running in "Accelerator" mode makes no real sense. But eventually I suppose I will need it.
